Well those things happened both times haha. But yes, first one is way further back, when Red Scarlet banned half the thread. The break off forum for that is pretty much completely dead now. The new one will have to wait a few years to die.
The first purge was when Red Scarlet went on a rampage and retroactively banned posters for posting crap from like 15 years ago. On a dare. I always thought she was a level headed mod but wow...that was some insane shit.
The thread has never recovered. Don't mind the troll Man U fans though to be fair, those guys dropped off real soon when the team went to shit like I predicted.
