Let me answer from the perspective of someone who is not a mathematician but follows this community for certain topics of interest. This is a community of professional mathematicians where, indeed, questions are usually very well researched and posed, and there's virtually no risk of rewarding homework dump. So, if there's a community in which questions' ...

I've looked at some related questions on Stack Overflow, Super User and Server Fault. On those sites, I found no evidence that voting patterns changed as a result of the reputation payout. Given the unique history of this site, it's interesting to see if we can see something different here. I'm taking June 25, 2013 as the transition date. As with the other ...

I don't see a problem with the system. It seems to me that any abuse of the system is by far the exception, not the rule. We need to be as encouraging as possible of the asking of good questions. A case has been made (see here for example) that many people, for example graduate students or assistant professors, find the atmosphere at MathOverflow ...

The question you answered is community wiki, and this also makes all answers community wiki. There is no reputation for votes on community wiki questions and answers.

I received a huge reputation boost from this change, but I still think that answering a question still takes much more effort than writing well-posed questions. Coming up with a good mathematical question is rather easy, one usually is in a specific situation, wants to draw a certain conclusion, so one adds a couple of assumptions that make obvious ...

By and large, the users who have created problems by flooding the site with questions have created equally many problems by also flooding the site with comments. This suggests that their behavior is driven by something other than the point system.

On my opinion, the site is flooded with bad questions (homework, trivial questions, poorly edited/illiterate questions etc.) People who ask them usually do not earn many points. On the other hand, people with high reputation usually ask good questions, so the reputation system fulfills its purpose to some extent. On the other hand, so-called "soft questions"...

I don't have a strong opinion on this subject, but insofar as I have one, it is this: Changing the rules is more trouble than it's worth. I lost points back when +10 was downgraded to +5, and I gained points when the +5 was upgraded to +10, and in both cases I was mostly annoyed that the rules had been changed for (what I perceived as) no good reason. So I ...

There have been discussions and ideas surrounding decaying votes, along with weights of votes themselves. I've got mixed feelings about both. It's important to look at the utility of reputation, the degree that the system trusts you, before you consider the extrinsic motivation that it provides. Believe it or not, having someone arrive to your site and ...

From my own experience, the worst questions on the site are usually homework problems, and these sure are not being asked for the sake of reputation. I sympathize with rep points for asking questions. These reinforce the concept that questions themselves are content and can have quality (or not). I feel that without this concept, people would write their ...

Let me first say that I'll try to answer your question generally, not to concentrate on the specific user you're looking for. So I understand the question as: "Is it possible to find user account in situations similar this?" (Also, I will try to answer this from a viewpoint of regular users. Moderators might have some more tools at their disposal. ...

They offered almost 4000 reputation in bounties so far this year: https://mathoverflow.net/users/8133/noah-schweber?tab=bounties Note that the -4827 is the decrease in rank, not in reputation, that's 'only' -129.

It is normal in the sense that I converted the question to community wiki before the downvoter downvoted.

This is due to voting irregularities that have been detected and corrected by the software. Apologies for the confusion. The users responsible for this have been contacted privately and asked to cease causing these irregularities.

This is a genuinely tricky question. I incline toward agreeing with the policy that while we can try to keep problems off the site while applications are open, we can't be expected to play whack-a-mole forever. This question from 3 years ago: Set of rational numbers generated by some rules was flagged as a PROMYS problem. My personal feeling was that this ...

The criteria are described exactly in What are the details on the "candidate score" which shows during an election?. Moreover, What would my Election Candidate score be? includes a link to a SEDE query that lets one compute their candidate score.

You wrote: For myself, on a completely personal level, I have noticed that I am less motivated now to ask well thought-out questions because they are "worth less". Is this experience shared? Can it be quantified? This is very surprising. I hope that this does not apply to most participants. For myself, the reputation on this site is completely irrelevant....

I think some of the difference is do to questions now being only 5 points. Also with MSE and stricter interpretation of research level, questions have become more technical which means there are fewer questions I can answer and when I do answer a question there are fewer people following the question to upvote it. I believe that my own accumulation of ...

If you click on the number "0.0x%", the links gets you to reputation league for MathOverflow. (The link given in the question is actually list of the registered users and not the reputation league.) As far as I know, only users from reputation leagues count for the purpose of these statistics. (That means that cut-off is at 200 reputation points. Notice the ...

There is daily reputation limit of 200 reputation points - meaning that it is not possible to get more than 200 reputation points in a single day from upvotes. (It is still possible to get more reputation points from accepted answers and bounties.) In this specific case, you got to 195 reputation points (some upvotes on questions worth 5 points, some ...

The recalculation is being processed in parallel across the entire network. Since it's run per user, some users on a site might get the change before others. We also had technical difficulties that have slowed the process down a bit. Hopefully it will be done for everyone across the network in a few hours. (Hopefully not days, but I can't rule that out at ...

The original question which was migrated gets automatically deleted after some time, so the reputation is deducted. What should really bother you is the question what is the voting data that gets migrated. In particular, can I vote your post on MO, and then vote it again on MSE (as the two votes are separate)? That would be counting reputation twice, but ...

It's not your user. Note that https://mathoverflow.net/users/56920/arnold-neumaier is a registered user who have no posts. Whereas https://mathoverflow.net/users/56919/arnold-neumaier is an unregistered user which has a single post with four upvotes, and 41 points of reputation. If you still have access to the unregistered account (through some browser ...
