Nov 24, 2018 at 11:54 comment added Stanley Yao Xiao mathoverflow.net/questions/316093/… looks like another one
Nov 21, 2018 at 23:56 comment added Yemon Choi @AndrásBátkai Yes, seems to be the same person
Nov 21, 2018 at 22:08 comment added András Bátkai @YemonChoi: And what about this answer? mathoverflow.net/q/315923

Nov 11, 2018 at 1:32 comment added Yemon Choi @NoahSchweber Typo, sorry: I meant mathoverflow.net/questions/314776/…
Nov 10, 2018 at 21:59 comment added Noah Schweber @YemonChoi That link gets a 404 - is it a typo, or did it get super-deleted?
Nov 10, 2018 at 18:52 comment added Yemon Choi @AndrásBátkai Looks like it, and once again we have a new user accout to deal with. Note that this new user mentions the paper of Bui et al which is also referred to in one the questions Stanley noticed: mathoverflow.net/posts/314776
Nov 10, 2018 at 16:23 comment added András Bátkai What abou this question? Is it related? mathoverflow.net/questions/315019/…
Nov 10, 2018 at 6:12 comment added მამუკა ჯიბლაძე I don't have a rigorous proof but I believe it is impossible in principle to machine-, rule- or otherwise automatically/formally recognize and block such cases. On the other hand I believe the community deals with them quite efficiently, with minimal intervention from the moderating team.
Nov 9, 2018 at 10:42 comment added Arnaud D. @StefanKohl I'm pretty sure I've seen that question in the HNQ, that could also explain the upvotes (especially since the association bonus is enough to upvote but not to downvote).
Nov 9, 2018 at 9:26 comment added Martin Sleziak Also I will add that if your post is mainly about this particular situation, the tag (specific-question) might be suitable. (See the tag-info for more details.) However, from the wording of the post it seems that links to the three questions serve merely as an example and you want to discuss this issue in general, not only this particular instance. (In which case, this tag is not needed.)
Nov 9, 2018 at 9:22 comment added Martin Sleziak It seems that in your first link you link to a comment rather than using link to the question. I am not sure whether it is intentional (whether this comment has particular significance) or whether it happened by mistake.
Nov 8, 2018 at 19:15 comment added Yemon Choi Hmm, it might be the same person (under different user identities), since the author of the questions Stanley is referring to has a profile linked to this other MO account mathoverflow.net/users/123416/user123416 and a physics.SE account responsible for this question physics.stackexchange.com/questions/424247/… on the DeBruijn-Newman constant which has the same level of misunderstanding as the deleted "DBN constant" questions on MO...
Nov 8, 2018 at 19:11 comment added Yemon Choi There was also some sockpuppetry related to recent RH-crankery - not sure if this is the same user... (don't have the relevant deleted questions bookmarked on this computer, can look when I get home)
Nov 8, 2018 at 16:36 comment added LSpice The question is no longer there.
Nov 8, 2018 at 14:19 comment added Stefan Kohl Mod I don't know how it comes that such question has 7 upvotes. -- Possibly there is some sock puppetry going on there.
Nov 8, 2018 at 13:54 comment added Stanley Yao Xiao @StefanKohl the question mathoverflow.net/questions/314776/… is still there, and has 7 upvotes. Typically such a question would be considered in good standing, so I am not sure what we're doing currently is enough

Nov 8, 2018 at 13:17 comment added Stefan Kohl Mod Do you think that downvoting, closing, deleting and flagging are not sufficient to avoid such posts cluttering the site?
