While looking at the read-only forums, the last messages from August of last year are from a Korean spammer. Can somebody turn on the old servers and delete that user's posts? They're probably banned by now anyways.
Sorry, but what's the point of that at the moment?
I don't approve of spam, but it's not like it's harming anybody, since forums aren't even working at the moment (like you said, they are read-only). Not to mention that even while the forums were active, it would take moderators around 12+ hours to deal with the spam anyway, so I don't see why would they bother to turn on the old servers just for that.
