yyy/superbad issue

As you all know, we had an annoyance from yyy/superbad.
The yyy account is forever-banned, and i've just deleted superbad.
All posts that say guest at the moment, are from him.

I'm going to ask a favor from mods. Delete all posts from/to yyy.

It will lessen up his spam.
Any double-posts because of it, I don't mind. Thanks.

Edit: Thank you Storm, I think they're gone. Yyy is deleted too.
