Hey there,
I've edited the post just to remove the actioned username. If that resulted in the account being actioned, please don't repeat it here either.
Regarding the ban itself, I'm afraid there is not an alternate route to appeal an account action. The only method to do this would be through our Terms of Service team, which it sounds like you've already done.
If they've reviewed an action multiple times and declined to remove the penalty, that would be final and not something we can change here either, sorry.
