How do you make an Appeal.

I was flying with leather armor on and I was banned for almost 2 months. It was my first day on the server and I was flying around the city checking it out. And some guy screenshotted me and reported me to a Trainee. (I was not using a hacked client is was a mod that allowed me to fly) I would like it if the ban was at least shortened I have almost nothing to do this summer and I've been playing on SUM servers for 2 years now. I had thought that I had found a loop hole because in the rules it said no hacked clients and this was a mod. I am sorry I've taken off the mod.
