I would appreciate if my account could be deleted. From other meta posts it seems that a moderator needs to do it. Thanks. I really see no reason whatsoever for not being able to do this ourselves just to put that out there.
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. If you ever change your mind, there's no guarantee you'll be able to get any of it back. So, y'know, we do try to make sure that's what you really want first. Some folks actually don't.
If you do, just follow the instructions and you'll find it removed fairly quickly.
