Over the past month I've gotten multiple unprovoked, unsolicited anti-American hate spam from user CyberGhost - or rather, apparently a hacker who has taken over his account. I don't have administrative user privileges around here, so if somebody can help out, that would be great. I bet an IP ban would take care of him.

For a look at what he's been saying, here's a transcript.

Why do we enjoy killing and plundering? It's simple.

EDIT: On a more serious note, I wouldn't actually be surprised if he wasn't hacked at all, I recall there being at least a few members of this board some years ago who actually made it their mission to spew hatred for the US of A at every opportunity.

Of course, I feel the same way about it that you do, in that it's usually just pretty amusing and only a bit tiring at worst.

Well, I suppose that's a possibility as well, although in a more recent message he explicitly said that he took over someone else's account and is intentionally trying to get him banned, presumably for being American.

Incidentally:
CG: How many innocent children have you killed today?
Me and my friend: Too many to count, don't get in my way!
