Well, checking the Block Log shows that any user sharing the same IP as "Harry Potter sucks" is being prevented from logging in. I did not chose this blocking option, and attempted to rectify it by unblocking, then reblocking him. Unfortunately, the "prevent other logged-in users with the same IP" remains checked for some reason. I'm shooting a message to Special:Contact for resolution.
