All you can really do is appeal, which it looks like you have already.
Just know that when you get a response on your appeal, it will be a template. Either upheld, overturned, reduced, or escalated. Escalation isn’t something you can request. That’s if the GM feels a deep review is needed. The GM who reviews the appeal won’t go into detail.
The Support Forum Agents who moderate the CS forum don’t review appeals and they won’t be able to provide you with any information as to what was detected.
