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 ...

Upvotes on questions now only contribute +5, rather than the original +10. There are a number of other changes, but this explains the bulk.

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"...

When a user is removed, their votes are removed as well. So the most likely explanation is that the user had voted for one of your answers and the reputation you gained from that vote was removed with the user. The cause for deletion is usually either sock puppeting and vote fraud, or the user reqested to be deleted. In cases of high-reputation users with ...

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 ...

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 ...

I should admit I don't completely understand why reputation seriously bothers some people. I think (and I think others share this view) that reputation is just there to make the system work (analogous to funding money for research) and provide some feed back, but other than it does not really mean much (though I have seen it causing some participation ...

See What is serial voting and how does it affect me? Basically, there are systems in place that prevent serial voting. For example, someone may find one or two of your answers as really good and upvote a whole bunch of others without reading1. On the other hand, a malicious user may give you many downvotes. Such strings of serial upvoting or downvoting in ...

I have a different suggestion: register as suitcase381, onionbag, probterob, or some other anonymous name, which you can change each year (if not each month). If you adopt an alter ego on MO then I don't see how reputation points would remain a concern. Other people have done that successfully.

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. However, ...

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.

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

There's a third option, which used to be used by ChrisF on Meta Stack Overflow for quite a while: He would post all of his answers as Community Wiki, thereby rarely gaining any reputation. This could be used as a viable workaround by those who do not wish to gain much reputation. Getting rid of all current rep can only be done via bounty. (or mass deleting ...

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 ...

I think the real problem is that "reputation points" on this site are not exactly about "reputation" among professional mathematicians. People discard they "reputation points" not to drop the "reputation", but to show they disagreement with the system measuring "reputation". I have the following proposal --- let us rename "reputation points" to "...

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 ...

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 ...

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....

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 ...
