This answer approaches the subject from more of a network level than a MathOverflow-specific stance. The Stack Exchange Terms of Service deal with this issue as follows: Under no circumstances will Subscriber use the Network or the Service to ... (c) create a false identity or to impersonate another person.... and also Subscriber may not (a) select ...

I brought this up with the moderation team in email; I haven't heard back explicitly from everyone, but have an idea where most of us stand. For now no official action will be taken. Putting aside the choice of name and avatar, there has been no detectable untoward behavior coming from this user, and the one post coming from that account so far has ...

Now that we've done the import, we'll need to refresh our global network cache of users and posts from all sites. The fun part is this is a huge job, so we have to take portions of the API offline for a bit to do it...which means we don't want to do it twice. Today we'll be checking that everything is ready for a backfill and we don't need to do anything ...

After some further discussion amongst the moderators, I think we have decided that this username and account photo are inappropriate; they seem to only serve to provoke controversy. I've changed both back to something generic, and notified the owner of the account.

What is the benefit to later readers in seeing the vote counts on answers A and B? Questions on ME sites are supposed to be interesting for non-expert readers as well. A layperson benefits from reading an answer that hits the nail on the head (at least more than from reading one that misses the nail entirely) but may not be able to recognize such an answer &...

When an account is deleted, posts made by that account on the main site with a negative score are deleted along with it. (Posts with a score ≥ 0 are preserved.) Previously all negatively scored posts on the meta site were also deleted, but this behaviour changed very recently and now all meta posts are preserved. All comments are preserved, although ...

I do not see how registration will decrease the number of poor quality questions. From time to time I look at MathSE, and the number of poor quality questions there is larger than here, despite the registration requirement. On the other hand, there is a class of people who really hate any registration, and this requirement can deter them. I am in this class ...

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 ...

I actually want to disagree with Todd here. I definitely agree that the first point of contact should be moderators@mathoverflow.net. We're friendly and helpful and want to resolve problems that generated suspensions or deletions, privately and constructively. (Of course, I would say that, wouldn't I? In any case, it's the truth.) But what should happen ...

What is the benefit to have such a system at all? For each question, there are many perspectives on it. Various presentations can reach wider audiences, if they are on topic, well written, and show some degree of relevance. The StackExchange platform is intended to encourage good questions that others can use, as well as good answers to those questions. ...

The reason is explained in this help center article. As the article states, the best step you can take next is to edit your existing questions. Unfortunately, you have several deleted questions with negative scores. But improving extant questions won't hurt. This activity might help you spot ways you could ask new questions more productively too when the ban ...

I won't describe the exact criteria the automatic question ban uses, but I will say we hope people will edit their poorly-recieved questions rather than delete them. We allow askers to delete their questions for the hopefully rare cases when people discover shortly after they posted that the question is inappropriate for the site and can't be recovered. For ...

As I said in a comment, the details in this case are strictly between the poster and the moderators. This is not a matter for public discussion, and there is not a bug in the software in this situation. The specific meta-relevancy and justification in keeping this thread open is simply to let readers who find themselves in a similar situation know that the ...

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, ...

See this page in the FAQ. As for letting people know, I'm not sure what you mean about that. I suppose that you can buy commercial time on the next Super Bowl, or maybe just some public access network, and let people know. Maybe a bus ad...

Please see this discussion, from the old forum 'tea' before it was superceded by MO meta: http://mathoverflow.tqft.net/discussion/1429/loss-of-a-member/ The discussion indicates that it was Anton Geraschenko who added the text. Related MO post: Wikipedia story about Bill Thurston's death.

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 ...

The request to merge was granted (thanks to a StackExchange Community Manager), and the question raised in comments as to whether the MO user named 000 coincides with Erin Carmody has been settled affirmatively to my complete satisfaction. It should be noted that moderators do not perform account mergers themselves; this is an action taken at the Community ...

You can find various search modifiers in the help center. Or simply by clicking on "Advanced Search Tips" after you search for something. Specifically, to find posts by a specific user you can user user:userid. And to find your own posts you can use user:mine or user:me. Notice that if you go to some user's profile page, the search query user:userid is ...

A subsidiary question: What are the consequences of an account deletion? Are all that user's votes, +/-, over all history, removed? Are all their comments, answers, questions, removed? Presumably not questions that have answers. Presumably not comments that might be embedded in a comment thread. Just curious. I am sure StackExchange has figured out ...
