FInally, I found the thread thay explains exactly my problem.
But I think wioth 3500 hours, I could be the guy with the most ingame-time here.
I tried to communicate with the ToS - Nothing: First mail-respond was:
We got your note and did a full investigation of your account. After reviewing your case, we determined that we took the correct action in accordance with EA policies and procedures.
What this means
We have confirmed that your account was involved in cheating. Because of this, we will not remove the sanction on your account.
second was in german but it was like
You just broke our ToS
Is the ToS-Team in our cases just checking, if we all are banned from the game?
So that would explain the answers, Oh the log says, you're banned, so it's correct, we'll do nothing.
I wrote a ~6000 letters answering post on a german thread, but it was closed befor it was sent.
I know you're here to help the community and you're not the ToS-Team, but please make them recognize, that there is a serious bug on there.
I'm working on a second part oft Stuff like that
But now, it will have a bit of a tragic highligt instead of gameplay. Feels bad.
