We recently demoted and permanently banned an administrator, Katydidit. He was having VERY inappropriate conversations with underage girls in private messages over Wiki Chat.
First off, it is important to state that Katydidit is a 48 year-old man. While this is not a problem by itself, he was having intimate online relationships with three underage girls on this wiki.
He exchanged emails with these users continually asking for pictures of themselves, asking to meet them, and constantly bringing up highly inappropriate sexual discussions.
He was told to stop his contact with the girls on the wiki, which he did. We then recieved complaints that he was engaged in highly inappropriate sexual conversations in Chat, via private messages; one of these conversations with an 11 year-old girl.
We created a decoy account, CreddieTandre; which was actually The Sam Puckett (Roxas82) undercover. She was posing as a 13 year-old girl, in order to screencap his exchanges. Here they are: http://s1100.photobucket.com/albums/g416/MeLlammoSammo/?start=all
I personally apologize for any distress caused by Katydidit's actions. These screencaps have been sent to Wikia, and we asked them to delete his account and permaban his IP address. We are still discussing sending this information to the authorities, since a middle school aged girl in real life may be at risk.
If any user encounters a situation where someone is asking questions, or saying things that make you feel uncomfortable, don't hesitate to contact an administrator immediately.
