Yes, the account in question has been deleted. (In general, accounts which are greyed out either belong to a now-deleted account, or, in the case of migrated questions, possibly to an account that was never created. When an account is deleted, the display name is reverted to the default user#### form.) Voluntary account deletions can happen in basically two ...

You weren't removed. What it means is that a user who had previously up-voted you has been removed. When a user gets removed, all the reputation they have given out is cancelled; from looking at your profile, it seems that someone up-voted one of your questions (giving you 5 points) and then their account was deleted.

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 ...

Yes. I put together the page Answers by deleted Math.SE users which organizers the answers by score, by user and by tags. How it works: Deleted users are listed in the decreasing order of the total score of their posts. Tags are listed alphabetically, with answer counts in parentheses (the tag counts are for all deleted users together). Answers are listed ...

As far as I know, we cannot get some data on dates of account deletions from the Stack Exchange Data Explorer (SEDE). Still, for deleted users we can find the date when they posted their last post. (Assuming they made at least one post. The same is true for comments. And also for some other actions - but I took posts and comments, since they are the most ...

In general, you can't know which user was removed, and which of your posts the removed user voted on. It is not under all circumstances impossible to find out beyond reasonable doubt, but one needs to make the right guess what to look for and where. Even moderators generally can't find that out. Most user removals that lead to reputation changes don't come ...

When an account is deleted, all negatively scored posts are deleted. However StackExchange employs only "soft deletion" which means that these posts still exist, they are just hidden to users without sufficient privileges. Such posts can be restored (if you can direct moderators or other sufficiently privileged users to their location for undeletion). (...

Is it possible to add some sort of way of knowing which posts were affected by the user's removal? I've described a procedure for this on Meta Stack Exchange. It uses the Stack Exchange API but does not require programming. Go to this page Change the site with the [edit] link (default is Stack Overflow) Click the 'Get Token' button so that the API knows it'...

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 ...

You can achieve this using a SEDE query. In particular using this query you need to enter the deleted user's displayname and the non-deleted posts will be shown ordered by their Score. For example this will be the result for the user you mentioned in the question.

Unfortunately, I think the stack exchange sites are being designed in the way that, this is the direction it will go (not necessarily a bad thing though). It is designed to be a Q&A site where eventually most commonly asked question can be easily searched. After years of effort of all the contributions from people, it's getting closed to the goal and ...

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 ...

User was removed vs. Voting corrected The message you received means that someone deleted their profile here or had a sockpuppet profile deleted. If you click on the link in your reputation history, it takes you to the explanation in the help center. It's worth remembering, many of these vote removals will have been from users who chose to remove their ...

To delete you account, go to the relevant help-center page and follow the instructions. In your case this amounts to follow the "contact us" link (as explained in a comment). Check whether you receive an email response and follow the instructions there. Then there may be a small wait, but eventually you account will be gone. (It may also happen more directly ...

It is most likely possible to have your old submissions attached to your new account, however this is an action that can only be done by those with access to the database: SE employees. Your best option is to contact the SE team directly with your request, explaining the situation as fully as possible. I know that deleted accounts have been reconstituted ...

EDIT: Originally I suggested using SEDE (see below). But probably a better option is to use some tool getting data about the usernames from Stack Exchange API, such as the one mentioned in the comments. (It is also mentioned in some other places - on this meta: To whom am I replying?, on Meta Stack Exchange: Make the “past names” list public info for 30 days ...

While I cannot speculate on specific cases, I've seen high-reputation accounts get deleted for a variety of reasons. For example, dissatisfaction with the site direction, disagreement with mods, getting suspended for irregular voting patterns. As for your suggestions to add a warning and grace period, I believe it's already the case. See this post for ...

If a question has an upvoted answer, then the question is answered. Acceptance of answers is still in the hands of the askers, and they won't necessarily oblige. There are many unaccepted answers in which the asker tells every answerer: "Thank you! This helped a lot!". How do you suppose we (as a community) subsequently determine which answers ought to be ...

You did nothing. Some user upvoted one of your questions, and downvoted one of your posts, neither of which was marked as Community Wiki. When the user account was removed, the votes were nullified and the reputation they gave you (positive or negative) was removed. If it makes you feel any better, I'd lost 28 points yesterday from a user removal, possibly ...

There just is no answer that was deleted. Note what it says (added emphasis): "This message means that a user who voted for one of your posts had their account deleted[...]" What happened is that a user was removed that had cast an upvote on one of your answers, and the ten points gained from that upvote were removed (to be precise, it could also be any ...

No, it is not possible to erase every content you posted on SE.

There is a related question on Meta Stack Exchange: How can I find posts related to lost reputation due to a “user was removed” message? Glorfindel's answer to this question provides a tool which can be used to find recent reputation changes, including the posts where reputation was change based on "user was removed" reason. (It relies on Stack Exchange's ...

When an account is deleted, all negatively scored posts are also deleted as part of the script. (There is a more serious destroy option which deletes all associated content, but this is basically only used on spammers and the occasional troll account which posts needlessly offensive material.) As such deletions are considered moderator deletions (that's ...
