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. ...

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 ...

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 ...

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 ...

It appears that another user has been removed, cancelling the upvotes the user has issued, thus negating the reputation they had given you. I too lost reputation today for that reason.

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 ...

As a relatively new user of this site, I would say that I would find it confusing and unhelpful if people were to have "multiple personalities". I would be constantly thinking about whether two people were actually the same person. I can't really think of any reason why having two accounts would be of benefit, apart from artificial inflation of reputation.

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 ...

The cancellation was caused by repeated infringing of rules. Cancellation of real users is a very unusual occurrence. Edit for clarity: Except in the case of SPAM accounts and sometimes sockpuppet accounts (used for artificially inflating reputation), moderators don't (at least as far as I am aware on Math.SE) delete user accounts unilaterally. So to ...

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 ...

In this case it was requested by the user. There is deletion and there is destruction. Deletion removes a user but does not remove any of their content which has a positive (non-negative?) vote total. Destruction removes a user and all of their content, but can only be done on users with less than 500 reputation. Not very.
