see no options in settings and such…

I think you basically have two options:

1. Put in a request for such with one of the admins.

2. Act like an asshole and get yourself banned.

You can delete your comics and other things, but only a admin can delete your account.

I seriously consider deleting mine about once a month along with the whole comic archive.

At this point, my entire account may as well be deleted from ComicFury altogether: my comic was deleted, my login was banned, clearly my home is here, there's really no point for my account to even still exist over there.

This really should have gone into the Help section here:

I can't delete your account at this stage because it's too old. I get a server error when I try :(

I can deactivate you but content stays… You have comments on comics that will still be there.
