SendEm hasn't really broken any rules, he just is repetitive with his hate for Iggy, and he has right to differ in opinion.
I've always been against banning someone simply because they have a majorly minority opinion, even if they are doing it just to annoy. The reason is because they spend a lot of time posting and contributing and banning someone pretty much is flushing all those wasted hours at the board down the toilet.
If you break rules though and are a major distraction then it is ok.
