Yes, in the FR forum thread that was linked elsewhere in this thread, Rhea directly talks about being involved. She was the one using the name and people reported it and got it banned because of her using it.

I definitely think it was a Bitch Eating Crackers moment, that only happened because so many people disliked her and wanted to find any reason to get her in trouble, and the fact that the admins reversed the ban after shows that. I don't remember many instances of a banned name being reinstated.
