I'm in the same boat as you all. I was permanently banned for "Game Enhancement," and the appeal was rejected with no explanation. I don't cheat.
I'm desperately trying to figure out what could have triggered it. I just got a new Alienware keyboard and mouse. I used the Command Center to set a keybind on a side button (like I always do) and turned off the RGB. I'm even wondering if just being clumsy and "overclicking" on the new high-profile keys could look like something suspicious. Has anyone else thought of something so minor?
It's maddening what we have to guess at because EA refuses to be transparent. They are punishing legitimate players who invest in their games and creating massive distrust.
