Machomedia forums seem to have been hit by a phpbb2 bot posting spam (of which some links to mpeg downloads that install a downloader trojan which is pretty evil to clear (I installed the trojan a few months back to see what it could do)).
Just a warning that if there is a new phpbb2 spam bot out it could inundate these forums too. It appears to target old posts, not the new ones and spam a ton of URLs in each post. I can see posts as far back as 2004 being used in the spam attack on the Macho forums.
I would recommend installing an antispam device to block this bot (something that requires a set amount of time before another post can be submitted). I am pretty confident that would weaken the potency of this bot.
Cheers
