Ban Appeal

I am posting this topic about my recent Gamertag ban from Forza Motorsport 4. I was recently banned from all online interactions for auctioning a modded tuned car. The only mods on the car that were not Forza approved was it was missing its bumpers. I had been given the tune from a former friend of Xbox by the Gamertag of [Mod Edit]. All of the other mods that had been don’t to it were all Forza standard modifications. The car in case was a Toyota Trueno. I am wondering if there is anyway that I can get unbanned from all Forza 4 online interactions. If there is, please say so on this post, or contact my email: [Mod Edit]
Thank you
