No one has any shells on the server. I'm just hosting my sites and a few other people from KWWHunction at the moment.

I know who the person attacking me is, and the reason he's doing it is because I refused to host him and his "scripts" when he contacted me on another forum.

Yeah, he is exploiting the phpbb3 database, that's for sure. I made sure all of my passwords are different for everything.

I'm going to give phpbb3 one more shot. Hopefully he'll get bored and stop, if not I'll just take the site down. It's no big deal, it just gets annoying restoring my site every other day.
