Never assume, especially when it’s not even for your own account that you’re playing.
No matter what anyone else has said or done, if a name is against the CoC/ToS, that’s it. Full stop. “False” reports, mass reports - does not matter. It only matters that per the GM(s) who have looked over your friend’s case, he’s breaking the rules.
And that if he’s at two weeks now? It’s not his first rodeo of bad naming choices and/or chat sanctions. He knows full well what’s going on, whether he agrees or not.
