There was a term for "creative" modding on a forum I lurked on. Moddake. It's a combination of the "Modding" and a word I'm not going to mention. Defiantly not a Pg-13 sort of thing, at any rate.
Examples: Changing the Name of a 13 year old member to something Along the lines of: ATTENTIONDEFICETDISORDERRRRRRR, and the word filter to change his previous name in conversations to the same.
Wordfilter changing Anime to "DERRRRGundam"
Someone who was named "Gavin(the sites owner)'s Girlfriend who was renamed repedidly.
And so on.
