I am really really sorry to post this on main, but apparently there's a minimum rep necessary to post on meta --- and there's no easily available info on how to contact the moderators.
I have hit the "delete" button a gazillion times, but this account (created very recently) will not go away, and its existence seems to prevent me from logging into my usual account. When I attempt to log into that account, I get logged into this one instead.
The help pages tell me to hit the delete button. That doesn't work.
I have tried the "recover account" link sent me by email, etc, but no matter what I do, I end up logged into this account instead of my usual. I have tried disabling cookies, but then I can't log in at all. As soon as I allow the cookies again, I'm suddenly automatically logged back into this account. Since the original cookies were erased, I can't figure out what's making stackexchange think it knows who I am, but it's extremely persistent.
