Tom is the dude that "invented" MySpace. He automatically puts himself on every new account so you receive the update bulletins and stuff. You can't remove him either, it's lame.
once, long ago, i removed tom because i didn't know who the fuck he was, and that very same day, tom messaged me about how sad he was that i removed him! the message was laden with "" emoticons and i felt really bad/guilty then, so i added him back and then we talked about riding burros in the desert. he said he would get me a burro. i don't think he's really going to get me a burro though.
i bet he used to scan everyone who removed him and, if they were a hot chick, he would pursue them. and maybe now he even locks hot girls from removing him.
