Looks like it. I could fix the site, or for that matter, port the database. But no one has responded to my emails.
I get a little pissed at forum owners who just let their site "die". Worst case - just give it to someone else. It is still costing him to host it - even if it is compromised.
I can "unhack" any vBulletin install. It just takes time and patience. Done it before, and can do it again. Even if the admin functionality has been hacked, he can regain control via his host.
