He didn't post screenshots of his profile so we have no idea what's on there, it's completely possible (likely, even) that his profile text did violate the TOS. Instant perma-ban might be a bit harsh but we have no reason to believe one side over the other and no evidence pointing either way.

He says he did nothing wrong anyway. They all do. Maybe he is telling the truth but it's hard to know.

Off the top of my head, there are at least two plausible explanations:

* Some user reported his account as "fake" or otherwise "inappropriate"

* The algorithm thought he faked his position

Neither one requires any intentional wrongdoing. It is what it is.

A naive customer support intern must have thought his last name “le fou” was fake because in English might sound like “le fuck”
