I'm totally not for the banning part. At least, not so damn long. However, if these are the rules when the next Pixelator comes, I'll just suck it up, and still participate. I've vengeance in my heart, and shall stop at nothing till I quench my thirst.
Also, if indeed this ban rule is put into effect, I think it would honestly be fair to have those who enforce them, participate within the tourney, and instead of judging, the winner would be decided by each user vote, kind of like Conceptart.org's C.O.W., or C.H.O.W., or whatever.
