The issue of this mega threads have been raised so many times. I personally do not think that a campaign have 50% of their post in gambling should complain about these mega threads. Besides the EPL thread for instance doesn't generate repetitive garbage as new discussions are always up to date due to fresh matches. As Despairo has noted, creating new pointless thread will constitute more spam.
When I said repetitive, that should be enough to clear what I meant.
