There are no rules against having multiple accounts. Part of the reason may be because it is very difficult to police such accounts, unless they are detected via voting fraud. If you wish, you can merge any of your accounts. Of course, if one of your accounts is suspended, using any of your other accounts is also forbidden. When this activity is detected, ...

Often, these deletions are handled by a single moderator, or even by an SE staff member, and the circumstances are not published unless the person requesting deletion decides to make the issue public in chat or comments. This is simply to protect users' privacy. You mention that SE encourages behaviors that offend good people. It would be easier to alter ...

The most important part of your question is not if we would allow it. The most important, and first question to make, is: "Would your university allow this kind of thing?". We cannot answer that, and that is something you must come in to terms with the relevant departments. If/when that is out of the way, then there is a lot of issues with this approach, ...

As noted in the comments, you can find instructions for deleting your account here: https://math.stackexchange.com/help/user-deletion Note that unlike some sites, we actually do hard-delete your account here - all of your posts are anonymized (they'll be attributed to "usernnnn"), your votes on others' posts nullified, your bio, preferences and such erased. ...

Looking at the UserId is a serious overestimate. The query SELECT COUNT(Id) AS NumberOfUsers FROM Users returns 82335, based on the data from October 13. (This includes both registered and unregistered accounts.) Since September 1, new users are joining at the rate of about 180/day, see new users per day. If this continues, the user base will reach 100000 ...

From a sample of several of these accounts, they do all appear to be the same user, who has not registered an account and seems to clear their cookies between each visit to the site. It would make sense to merge them. However, moderators can no longer merge users; it must be done either by the user themselves or the StackExchange team. Since there does not ...

Unlike with attribution, where you have to supply the name of the creator and attribution parties, a copyright notice, a license notice, a disclaimer notice, and a link to the material. CC licenses prior to Version 4.0 also require you to provide the title of the material if supplied, and may have other slight differences. (copyright, license and ...

From the top of my head: Ilmari Karonen is the maintainer of SOUP that patches various glitches on SE-sites, some specific to this site. See the user page for details. robjohn has developed a tool, known under the name CatChase ChatJax, so that math renders in chat. As far as I know it is widely used, and makes chat a lot more useful for some. See a meta ...

I challenge your assertion that "a great number of persons that have been created an account because they were motivated to learn and share mathematics". My guess is that a large majority of the people who create accounts on MSE do so in order to get a couple of homework questions answered right before a deadline. They don't care about maintaining a ...

The numbers are assigned consecutively to all accounts created on the site. With one exception, they are positive integers. The first accounts are created by SE developers in the process of putting the site together. Geoff Dalgas is user number 2, and there is no user number 1 (I don't know why). The first "real" (non-SE-affiliated) user of Math.SE was Noah ...

It is allowed to have several accounts as long as you do nothing with those accounts that in essence you could not also do with a single one. Some examples of things not to do: Do not use a new account to evade a suspension or ban. Do not vote for posts of your other accounts. Best, try not interact with posts of your other accounts at all. Do not use ...

No, on a per user basis it's not a new record, not even close. See the point-timeline of Brian M. Scott around end of March this year for a recent loss an order of magnitude higher. Yes, for 'large' accounts votes are often preserved. Actually the criterion are the votes cast, not the points of the user, considering both the absolute number as well as the ...

It is no longer possible to ask questions with an unregistered account on Mathematics Stack Exchange. The change was made on or about 10 Oct 2016, at least in part in because of the response to the feature request Let's require registration to ask a question (see Grace Note's answer to that question). (Users can still answer questions without being ...

To find posts by a deleted user if you have the userid you can use Data Explorer (SEDE). See also: Is there a way to check all questions/answers posted from a deleted account (MathOverflow Meta) and Shadow Wizard's answer to Why not keep anonymous profiles accessible? (Meta Stack Exchange). Some examples of SEDE queries: Get posts list of a deleted user ...

Yes. It's possible. People can open more than one account, and some people do. If both accounts have reached 3,000 points then both can vote to close. The SE software does its best to disallow a user to abuse the system in the form of two accounts acting simultaneously towards the same goal. If a user has voted twice to close a question, or voted twice for,...

The help center contains a page with instructions for how to do it. Since you have significant contributions to the site, you contact Stack Exchange and request the deletion of your account. You will be told what further actions you need to perform to ascertain that it's really your intention to have your account deleted, and when those are done, your ...

UPDATE: To keep things interesting, I brought this up to the SE gods. After a period of time, we learned something: There are trusted openID sources, like facebook and gmail, that easily associate with your MSE user credentials. You can have different MSE accounts with different associations. But if you have two different accounts, and they have the same ...

For entertainment and for more serious purposes, here is a CW list of the known names and results. The case of known censored substrings is omitted; they can be detected by a script and the results are more predictable. Move cursor over spoiler-space to view.

Just to see how StackOverflow views this issue, I looked up a few discussions of offensive usernames and gravatars on MSO. They might be applicable: Possibly offensive usernames Inappropriate username and/or gravatars. Offensive Username

There are some problems with this suggestion: (1) it makes sources of posts less readable (/portable); (2) what should happen when one user edits other user's post? (3) including a lot of command definitions in all user's posts certainly won't make processing of MathJax faster. Somehow this feature request reminds me of the Tower of Babel.
