STUPID QUESTION! Why do you think this guy would make a fake myspace, add me & then not even talk to me on it?

let me clear something up: he made the account for me... to pretend it
was some random dude requesting me, but my i tuition told me right
away is him, or someone that i know.
so, i decided to go along with it and pretend it was just a random guy
requesting me, and i accepted the friend request.
i was awaiting a message or comment saying hi or something...usually
fake myspaces want to interact with you.... but it has been 2-3 days
now and i haven't gotten anything from it.
what do you think is going on? what shall i do?
