If specific GMs are involved, who are seemingly close to someone I'm having a spat with on the forums, would make me question whether I am being treated fairly compared to everyone else involved and that should not be the case. This is also why the 'appeal' system does nothing for me. I can only appeal decisions against me (which I may believe are justified), not against others involved which I know nothing about.
It's really quite simple.
1. If you feel you've been wronged by a GM decision, you may appeal.
2. If you feel someone else should be punished, you may report them.
3. If you want to know if/how someone else was punished, as a rule that information is not divulged.
