I have my enemy's facebook password. What now?

[jun]

This kid who has been bullying me ever since sixth grade jumps me every single day with his scumbag gang, and only makes my life more miserable than it already is. And you would probably think the school counselor would possibly try help, but that's really the only case if the counselor was ever at her desk. And don't even get started on my parents, I'm basically a background image to their fighting everyday. Anyways, thanks to the dimwit brain of the bully, I have successfully obtained his facebook password through the use of a keylogger. Is there anything I could do, just to mess around with his brain?

I don't think that would do me any good, and it would probably only make him even angrier to know that I'm the one who has his facebook password.
