I have seen quite a few posters getting banned so that statement is not at all true. You can say they were trolls but that would be beside the point.
Anyway, I'd never report anything to the mods no matter what. I've been on different forums since 1998 and I've never once done it let alone tell anyone that I would. I wouldn’t take things that far especially when I know at least a bit about a poster.
Yes, they were all trolls.
If Mark actually believed in modding (not just banning), then James/Clydey would have been banned long ago. Or at least modded constantly.
