BOOM BOOM HELLO INSTANT MESSAGE

I returned to my dorm at around 5:15pm today only to see the following IMs sent to my away message:

mel ittens: OMG
mel ittens: OMG OMG
mel ittens: UBER HAX0RZ
mel ittens: I HACKEED U RMOM PUSSY

I have no idea who "mel ittens" is, but I assume he/she is German.

By the way, I've checked, and my "RMOM" is fine and unhacked.
