I am sorry to see that you pulled a TubaDiva. It doesn't work like that. You have to accept that this discussion is not only about the ban but also about your conduct during the whole affair.
So I have a few questions:
Is it possible that your moderating standards slip once you are personally affected?
Considering what you suggested to Exy, do you still maintain that you banned him because he harms the board?
Can you see how this leaves you with a slight credibility problem?
I know that you won't like this thread. Lock it, delete it, ban me -- it will help less than you hope.
