Jul 21 '19 at 11:41 comment added David Roberts It seems the flood has abated...?
Jul 12 '19 at 21:39 comment added YCor @AsafKaragila thanks, this seems quite convincing that the name Denis CdL was a pseudonym. However it seems clear to me from his mathematical background that he's distinct from the recent multi-account user.
Jul 12 '19 at 16:02 comment added Asaf Karagila Mod Paging @StefanKohl :-)
Jul 12 '19 at 16:01 comment added Robert Furber @AsafKaragila Yes, I should probably have addressed my comment at Stefan Kohl, I was trying to affirm the idea that the original Denis was not related to the current user creating and deleting loads of pseudonymous accounts
Jul 12 '19 at 15:59 comment added Asaf Karagila Mod @RobertFurber: And following the discussion here, it seems to me that this might not be the same person who created all those other accounts. Not to mention that all the accounts of "Denis" were always using the same name (and supposedly the same email, judging by the consistent Gravatar across the accounts).
Jul 12 '19 at 15:57 comment added Robert Furber @AsafKaragila In a comment here: mathoverflow.net/a/63433/61785 Kevin Buzzard hints that Denis Chaperon de Lauzières might actually be called Emmanuel. There is a certain Emmanuel who wrote a blog post saying MathOverflow was silly and he would only contribute to it under a pseudonym.
Jul 12 '19 at 12:51 comment added Asaf Karagila Mod Regarding the new edit by @YCor and the mention of Denis Chaperon de Lauzières, the unregistered accounts go back at least as far as 2011, which makes me uncertain that this is directly related to the current state of affairs. (You can find on tea a request to merge four unregistered accounts, one of which became the one linked in the edit.)
Jul 12 '19 at 10:40 comment added Stefan Kohl Mod As to @YCor's recent edit -- googling and searching on zbMATH, I cannot find evidence that there is a mathematician named Denis Chaperon de Lauzières at all.

Jun 24 '19 at 0:41 comment added user135665 Then take a few months off from Mathoverflow. Do enjoy learning, in the more traditional “books and exercises” fashion. I wish for you to get to see by yourself how much this will pay.
Jun 24 '19 at 0:41 comment added user135665 at the potential cost of jeopardizing his immediate future, is something I’m having a very hard time understanding. Everybody makes mistakes: what’s important is to draw a lesson from them and turn them into, precisely, “a positive drive for change”. I’m hoping you’ll take the following suggestion in a constructive way, and act on it, after taking some time for yourself to reach this conclusion on your own: leave a short message to the Mathoverflow community, down here, apologizing for causing so much confusion, and unnecessarily wasting a number of people’s time.
Jun 24 '19 at 0:41 comment added user135665 Let me point out that the disrespectful conduct you’ve been showing, does not match the one that would be expected from a person that is soon due to become part of a school that, among others, values character and moral fiber, and the capacity to bring to the table a positive drive for change. It happened in the past that your future school rescinded admission offers due to unbecoming conduct, and very recently so. Why would a bright young man spend his time in this fashion, and why so persistently and unapologetically,
Jun 24 '19 at 0:40 comment added user135665 While this is admirable and potentially fruitful, provided your eagerness is harnessed the right way and accompanied by humility and patience, with the aim of not burning crucial steps in your learning process, you seem to have yet to fully appreciate how inappropriate your behavior has been so far, and that this may reflect badly on you in your nearest future. It seems you’ll be soon starting your freshman year at Harvard.
Jun 24 '19 at 0:40 comment added user135665 @prf I have not owned a Mathoverflow account for a long time. A student of mine, whose account I am borrowing, for this once, brought this situation to my attention, and after some thought I believe it may be proper to point out to you a few aspects that I'm afraid you may be overlooking along the way. I will do so myself, in a way that I hope you'll read as friendly and benevolent, since it is. According to your personal CV, assuming your identity has been correctly singled out, you seem to be a bright young student, eager to dive into advanced material and keen on teaching it to himself.
Jun 23 '19 at 18:10 comment added Samir Canning mathoverflow.net/questions/334638/… concerns me. I answered the question because it seems legitimate, but it’s getting downvoted as if the person who asked the question is the same as the one who is making all the accounts. This isn’t good because it can scare legitimate new users.
Jun 23 '19 at 17:56 comment added Yemon Choi @GetOffTheInternet user130022 doesn't quite "smell the same" to me but I could be mistaken
Jun 19 '19 at 16:55 comment added Steven Landsburg @Emil : gone in under 16 minutes, I'm very glad to see.
Jun 19 '19 at 16:37 comment added Emil Jeřábek A brand new Asura Path: mathoverflow.net/users/142104/asura-path .
Jun 14 '19 at 2:21 comment added Steven Landsburg @ToddTrimble: once again, I'm very glad you're on this.
Jun 14 '19 at 2:17 comment added Todd Trimble Mod @StevenLandsburg Yeah. I've now got some Community Management looking at the case, and we're pretty much in agreement with what's going on. Meanwhile, a very large number of accounts have been deleted.
Jun 14 '19 at 2:12 comment added Steven Landsburg @ToddTrimble: yes---and as I'm sure you've noticed, he's arrived with an association bonus.
Jun 14 '19 at 1:51 comment added Todd Trimble Mod Hi: mathoverflow.net/users/141869/phd
Jun 13 '19 at 10:33 comment added Jeremy Rickard A veritable meteor shower of incarnations of "phd" this morning. Another one (user141854) shone for a very few minutes and burnt.
Jun 13 '19 at 8:27 comment added Jeremy Rickard @JoelReyesNoche That was (at least) the third incarnation of "phd". It has since been (self-?)deleted, and then very briefly (a few minutes?) we had phd number 4+, (user141832) again arriving with an association bonus, but apparently deleting themselves after posting a few comments.
Jun 13 '19 at 6:28 comment added Joel Reyes Noche Another one: meta.mathoverflow.net/users/141826/phd . This one got a 100 point association bonus (16 mins ago?) but only has one account (MathOverflow).

Jun 11 '19 at 9:18 comment added user141498 @DenisNardin by the way, please avoid making unfair accusations (I think the one you have made was unfair, see the previous comment). I want all discussions on MO to be civil, honestly. But since we have started this already, it is suspicious that you make unfair accusations against people with a different opinion.
Jun 10 '19 at 22:38 comment added Todd Trimble Mod Because that account doesn't fit the pattern we're seeing. I don't see why it should make any difference to you, if you claim you have nothing to do with these other accounts.

Jun 9 '19 at 20:52 comment added user141498 @WillSawin I don't know, I guess everyone has their own reasons. I am personally just annoyed at the fact that a user can only have 3 bounties at any given point of time.
Jun 9 '19 at 20:51 comment added Will Sawin @AsuraPath if not for this reason, then why create so many accounts?
Jun 9 '19 at 9:40 comment added user141498 @YemonChoi In fact, if your sole purpose is to ask as many questions as possible, the best strategy would be to get your account 125 reputation points, then there is no limit; it is definitely not to create many unregistered accounts. Given this information, I can not understand the point of a part of your comment, I hope you can clarify.
Jun 9 '19 at 9:40 comment added user141498 @YemonChoi "I also find the creation of "one-shot" or "burner" unregistered accounts solely for the purpose of a high-volume of questions verging on obnoxious spamming": if you are referring to the limit on the number of questions a person can pose in a given time frame (one question in 40 minutes, I think), then that limit is enforced on the level of IP address (can the more enlightened confirm this?). So merely creating many unregistered (or registered) accounts will not allow you to ask questions at a faster pace than you could using a single account.
Jun 6 '19 at 13:39 comment added Steven Landsburg @YemonChoi : Agreed on all counts.

Jun 6 '19 at 12:56 comment added Yemon Choi @StevenLandsburg What I find vexing is that to my non-AG eye, some of these questions look reasonable; but I really dislike the disingenuous behaviour of different user accounts interacting as if they are different people, even if this does not involve voting. I also find the creation of "one-shot" or "burner" unregistered accounts solely for the purpose of a high-volume of questions verging on obnoxious spamming
Jun 6 '19 at 12:53 comment added Todd Trimble Mod Thanks to @WillSawin and Steven. I had to look up Naruto/Nagato, but FWIW, see also en.wikipedia.org/wiki/…

Jun 6 '19 at 11:09 comment added Steven Landsburg Adding this comment to insure that @ToddTrimble sees the two preceding comments.
Jun 6 '19 at 10:58 comment added Denis Nardin @WillSawin There are indeed six users with names of the form "... Path" (Human Path, etc.), all with the same description. I don't think awarding bounties on each others' posts is against the rules, but it is skirting the boundary (and jumping right past it if they use it to artificially decrease the costs of the bounties).
Jun 5 '19 at 21:45 comment added Will Sawin On Deva Path's user page, I found this strange but seemingly relevant quote "The Six Paths of Pain are controlled by Nagato. The Six Paths of Pain do not answer, upvote, comment on each other's posts. The Six Paths of Pain award bounties on each other's posts." If the Six Paths of Pain refers to this group of users, this is according to what Todd said not completely true. This is apparently a reference to Naruto?
Jun 5 '19 at 6:18 comment added David Roberts @DenisNardin this is backed up by the FAQ: Do your homework Before asking your question, try to solve it. Search Google, Wikipedia, and nLab, check any references you can think of, and try to figure the problem out yourself (maybe even sleep on it).
Jun 4 '19 at 15:24 comment added Denis Nardin @cardinal This is probably OP, but I cannot imagine posting a question on MO without spending at least a day thinking about it to see if it is really nontrivial. And even so, I'd probably spend at least 20 minutes writing the question, to make sure I am satisfied with its formulation. In this light, you'll see why your "someone could produce a question every ten minutes" strikes me as ridiculous at best.

Jun 3 '19 at 13:02 comment added user74900 @StevenLandsburg your comment is slightly ambiguous. I never said I personally generate any interesting questions but I guess you mean in general. I agree with the general statement though I do not see how is it relevant here.
Jun 3 '19 at 12:59 comment added Steven Landsburg @cardinal : The fact that you've "generated an interesting question" is not sufficient reason to post to MathOverflow.

Jun 3 '19 at 9:43 comment added user74900 I don't really understand your "positive(!) way" statement. If you could clarify what exactly is your problem with that, that might be helpful. I am not sure what opinions of mine are adjacent to whose, and my mathematical interests are not exactly rare or unusual.
Jun 3 '19 at 9:41 comment added user74900 @YemonChoi I see via inbox that you (I think) have posted some replies to my comments there but unfortunately I can not read them because the question has been deleted. I did indeed mention setting up a bot because I do believe that some people can generate interesting questions at a rate faster than once per 40 minutes (you probably heard about some very smart people in your life and I have also seen some) and there is nothing wrong with that, as long as the bot obeys the rules. You seem to be insinuating something without making explicit accusations and I do not appreciate that.
Jun 2 '19 at 13:35 comment added Yemon Choi Steven: if you look at the comments on this deleted question meta.mathoverflow.net/questions/4243/… you will see some user with certain opinions/interests adjacent to the present discussion mention, in a positive(!) way, the notion of having a bot that queues up a bunch of questions - could this account for the pattern here?
May 21 '19 at 17:09 comment added user138661 @AlexM. OK, that is your right.

May 4 '19 at 11:13 comment added user138661 @MartinRubey I would love to see the code if all of these were written by a program. It got at least some of the semantics right.
May 4 '19 at 7:14 comment added Martin Rubey I wouldn't be very surprised if (at least some of) these are a computer program.
May 2 '19 at 19:59 comment added Gerhard Paseman @Steven, I don't think I am overlooking the issue so much as waiting for you to clarify it. While it is good to engage with the original poster for clarification or increased understanding, it is not necessary. If someone comes along later and contributes well to the post, that works too. In either case, you are the judge of how worthy the post is of your time. Gerhard "Have You Some More Concerns?" Paseman, 2019.05.02.

May 2 '19 at 15:12 comment added David E Speyer @StevenLandsburg I don't think either of us are disputing each other; I just want to make sure people who are looking at this thread have a good understanding of the situation.
May 2 '19 at 15:10 comment added Steven Landsburg @DavidESpeyer : I do not at all dispute that the questions are reasonable and in several cases interesting. I even answered one of them!
May 2 '19 at 15:09 comment added David E Speyer I would like to say in defense of these questions that several of them are interesting, such as mathoverflow.net/questions/330337 , mathoverflow.net/questions/330178 , mathoverflow.net/questions/330168 , mathoverflow.net/questions/330159 , and all of them are at least reasonable. This is different from other times when we've had a flood of what are clearly low level homework questions.
May 2 '19 at 14:32 comment added Wojowu Possibly another to add to the list: mathoverflow.net/q/330539/30186
May 2 '19 at 13:59 comment added Gerry Myerson OK. I asked because of mathoverflow.net/questions/330156/… posted by mathoverflow.net/users/139941/fatpoint (so maybe fatpoint should be on your list?)
May 2 '19 at 13:41 comment added Steven Landsburg @GerryMyerson : I did copy these by hand, so there could be typos, but it does seem to say faptoint.
May 2 '19 at 13:16 comment added Gerry Myerson faptoint? Do you mean, fatpoint?
May 2 '19 at 10:51 comment added Andrew T. Having multiple accounts is not really prohibited. But it's a different case if it's used for malicious purpose, like trolling, avoiding ban, or even voting fraud. At this point, mods can check if they are related or not, and do something about it.
May 2 '19 at 10:37 comment added Gerald Edgar Another explanation might be: MO was mentioned by the instructor in some math class somewhere, and as a result 10 of the students decided to try it.

May 2 '19 at 3:33 comment added Martin Sleziak BTW the users you mention are unregistered user. Registration would decrease the likelihood that the asker looses access to his account. (Although it's not clear whether this is what happened here.) Past discussion related to registration: Should MathOverflow require registration to ask a question?
May 2 '19 at 3:30 comment added Martin Sleziak I have added (new-users) and (multiple-accounts), since they seem to be suitable tags for this question. I wasn't sure whether to add (specific-user) - probably not, since the question seems to be mostly about the general issue rather than about this particular user(s).

May 2 '19 at 0:26 comment added Steven Landsburg Gerhard: Well, one issue you're overlooking is that I might not want to put much effort into this person's questions in the future, given the likelihood that my responses will be ignored. If the username keeps changing, it's a little harder to identify the questions I prefer to skip by.
May 1 '19 at 23:42 comment added Gerhard Paseman I agree that there are differences. However, it is the behaviour that should be the focus. If there are thirteen hit and runs which result in thirteen average but worthy questions from which the community can benefit after improvement, that is better than one individual who gives thirteen poor questions and does not get the message on how to improve them for the forum. Gerhard "How Good Are The Questions?" Paseman, 2019.05.01.
May 1 '19 at 23:16 comment added Steven Landsburg @GerhardPaseman : There are some relevant differences, though. For one thing, I'm not counting "accounts on the Stack Exchange network"; I'm counting accounts here on MO. For another, you have multiple accounts under names that are recognizably yours, which seems a little less suspicious. For another , your multiple accounts did not (I believe) all spring forth full-blown nearly simultaneously. And for yet another, you have no substantial history of hit-and-runs, where you ask a question, a commenter responds, and you're never heard from again.
May 1 '19 at 22:55 comment added Gerhard Paseman I have over ten accounts on the Stack Exchange network myself. (This account is the one that I use most frequently as of late.) While I understand your concern, I think the content of the questions should be the issue, not the manner in which they were asked. Also, as user names can be changed, you might list user IDs instead. Gerhard "No, I'm The Other One" Paseman, 2019.05.01.
