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.

write on your own wall pretending to be him. apologize and say how he will never hurt or bully you again.

write on his wall as him, saying stuff like, "hey guys i didn't tell you before but i have a crush on *name of girl who you know hates him and will embarrass him* " or if his parents have Facebook, write on his wall, or to his parents' wall, " fuck you dad (add more bad words and stuff) " to get him grounded. or if your teachers have Facebook, type bunches or swear words on his wall as him, and your teacher's will see you and punish him next day.
try not to make it too dumb or it'll just be funny, and won't truly embarrass him. oh, and change his favorite movies and stuff to girly ones like mean girls or hannah montana. not my little pony, because it's just funny, but not embarrassing! or if it is embarrassing in your school, choose it, and pretend that he likes those movies. choose some girly singers too.
for pictures, put bunch of pictures of hearts, flowers, cute stuff, puppies, ponies, etc, and his profile picture too. but don't exaggerate. we want it to be super realistic, so people actually think it's him, and bully him! awesome strategy, right? not exactly destroy him, but just a give him to taste his own medicine, a bit.
