Hack-daddy

I've received numerous messages today that my myspace account has been hacked! Apparently, I've been sending messages that go something like this:

You gotta send my friend a message. She thinks your really CuTE! Addher on (MSN)Messanger [e-mail address].

I don't even understand how hacking works. Or why someone would want to hack into a myspace account. Or why anyone would think that my friends would want to add some girl named "Emily" to their myspace friends. Or why "CuTE" is an acceptable or interesting way to spell a word.

Does this have something to do with porn? Oh, Internets, you confuse me.
