For TeamInfidel: note the almost 40,000 posts.
For P80:
I'll try to make this as quick and simple as possible.
The political forum was having some interesting debates, many of which got a bit "heated" (look back in the political forums or look in the hall of shame to see exactly what was going on. the mods even completely shut down the political forum for a couple of weeks to sort out the mess) P80 got temporarily banned a couple of times for flaming other members. He got the permanent ban when he attempted to post a file after asking Redleg whether he could post it or not (Redleg said no). With that the plug was pulled.
Three strikes, and he was out.
