Yeah, it was a spammer. We've had two make it through the registration challenges this week, and they then flooded every thread, old and new, with advertising posts in japanese. No idea why, seeing as nobody can read them....

Anyhoo, we now require a moderator to approve new user registrations (only takes a few moments, and it's totally obvious who are genuine users and who are spammers), so we should hopefully not see a repeat of this crap. I'll look at restricting IP addresses again too, to just not have the site visible at all to most of asia and europe.
