simple solution: add an Alternate cryptocurrencies -> Monero board. any mention of monero outside of the ghetto is verbotten.
This would be unfair to other alt coins. The best solution is for Monero to get their own forums like every other Alt coin has. Either that or consolidate all Monero talk into one thread, like the Anoncoin chat thread does for instance. Notice no ones trolling them.
You do realize that Bitcointalk is becoming obsolete do you? I'll see you over on Monerotalk but I can assure you that it's probably going to ban/censor shitcoin talk like any civilized place would do.
