This is going meta-meta, hold on tight..!
There seems to be 3 tags that have to do with account/user-deletion:
deleted-accounts (221 questions as of writing):
This tag is for questions about user accounts that have been deleted or the process of that deletion.
deleted-users (27 questions as of writing):
This tags is for questions about deleted users.
and account-destruction (2 questions as of writing) without any excerpt/wiki.
I'm not sure about the account-destruction, but it seems it's focused more on spammer (or any abusive) account/user. Does this tag deserve to stand alone, or should it be burninated/synonymized too?
