It's sending Lisa Peachy images now to hook you up. As I'm not so fast to follow links in messages from stranger, I've checked it out at google image search. And whatever I say (I've asked about monitor settings from image), it's going about this "private show just for you, and you ned to register with credit card just to prove your age".
PS: forgot to mention, this bot asks you about your username to add you to it's friend list - then how it messaged you without knowing your username?
