Oh please, Cettie was a moderator and feeding private information about people to Sybil and others for years. She just made the mistake of saying something publicly and it got her banned. I'm sorry but she was not the wonderful person some thought she was. There have been insinuations by some that she is behind some of the troll accounts that have popped up since, but I have not proof of that and no clue if it's true or not.
Sybil also got banned slightly before and several others were given reprimands all for abusing the downvote system and sharing private information among themselves feed to them by Cettie. I am going to assume the other moderators were not involved. Several of the people mentioned in this thread were involved and just chose to not come back or come back sporadically after being reprimanded.
