I'm not sure if the bug was actually fixed or if I was unbanned from whatever subs that banned me. I know my account was recently unbanned from sbbh, but I am pretty sure I was still banned from a couple of Henrycorp's subs.
Either way, it's worth checking out if you were previously unable to delete your stuff.

Edit: Never mind, I must have been unbanned from whatever subs. I tried an old alt from my days of bugging sanegoat and it still gets the "globally banned" warning.
Did you get an unbanned message from a sub recently?
