I am sad to hear that this happened to you. Though it is hard for us staff members to actually be sure what happened since we were not in the game with you. The best thing you can do is to actually appeal and try to explain everything that happened both before and when you got banned. Explaining what might have caused it or provide what modifications you were using, if any, as well as any other useful information.
If your appeal gets denied, you should also be able to discuss it. Sadly nothing else can be done about it.
Also going to move this thread as it is not a suggestion or feedback.
