I am working on migrating a PHPBB forum for a client and have exported their posts table. I looked the SQL over and there's all kinds of random stuff—posts in Swedish (it's an English site), posts about random completely unrelated topics, etc.
I can't tell if these are spam posts and, if so, is there a way to find them and clean them up? I don't see any of these posts in the public facing forum. Any thoughts on what's going on?
