BJ - the times I have been replying to your off-topic posts I think I have been pretty accurate in knowing what you've been up to, right?
If you want to know who it is, I am pretty sure I can figure that out and other info and even do some malicious things but before you go off in that direction, I can tell you that it is probably someone from your school or one ring outside your circle of friends who is having sick fun at your expense.
The better thing would be to forget about it and block the person from sending you IM's. This will get them more upset than anything else. You will find that the world is made up of all kinds of people. You can't control what they do, but you can control yourself.
Boy, before there was the internet and IM, we had prank phone calls, followed by stand-offs and knife fights, shovels, searched for bodies, court arraignments, prison time, etc... but I digress. See how technology has changed the world? You can avoid all that and just hash it out on a computer without resulting in prison time. heh heh heh heh
