how to make justin bieber follow me on twitter???

You have to keep spamming him, he doesn't get to see them all, so keep posting it (;
 ex: @justinbieber You should follow me, it would make me a happy camper (; Haha, I'm naming you Uncle Skipper :0 That's yo new name (; ;@justinbieber when hes on! or if you get his fan mail adress from a magazine and tell him to follow u he will <3
