The username above contains a personal attack towards one of Russian Wikipedia sysops. Both attacking word and user's surname are forbidden in [[ru:MediaWiki:Usernameblacklist]], but such accounts can be still created with SUL. Global blacklisting is not helpful here, because (1) we are not always able to wait for a meta sysop and (2) global checks may prevent a fair registration in another project, because a word that is offensive in one language may be quite normal in other one.
Therefore account autocreation should be forbidden if the username is blacklisted locally. I can't currently think of what will be the best — just leave the user logged out, or create the account and automatically block it — but the current situation definitely has to be fixed.
