Recently I have seen someone on emc get banned who I do not think should be. Can other people pm ICC and help?
Yes, I understand that, and that's great. The answer to your question is, PM mods to discuss it; don't discuss it here.
If you have any evidence that could help in an ultimate ban decision, staff welcomes your input. If you simply want to beg along the lines of "so and so is my friend and I hate playing without him/her" then not so much.
