The_Element acted as a good person and then suddenly raged and did this: http://s903.photobucket.com/albums/ac232/Tigerboy5225/
He did all of that. I know it's not much but if he hadn't left immediately, he would've done more. I am just telling you to be cautious or be smart and ban him.
Do you not have backups? I don't think this warrants a thread, unless The_Element was a well known user of the Minecraft community gone bad. People grief all the time and we as server admins act on it and are used to it, if we had a thread made for every griefer this forum would basically be getting DDOS'd from all the connections of new threads being made.
I agree that I'm tired of seeing these. Unless there is reasonable evidence (e.g. videos of the griefer, pictures, claims from multiple servers), it's just unfair to the player being blamed. I personally don't ban anyone until they break the rules on my server.
