I'm pretty sure that milliondollerpie was banned under quite a few names. Vladpie is another who was red carded under more that one name.
I don't know if tarquin is banned or if he's just decided the board isn't for him.
Soccerman166, who is now Joe Pass, was banned but I think it was when Tricky's mate Romanis managed to become a mod on here. Back then many were banned including me, but thankfully that was all put right.
