How to get people to stop calling?

My friend as a ''joke'' ecided to post my moblie number on a social networking site, nothing happened for a while, but then this weird pervy guy started texting me, I pretend I was a lad and tied to scare him off, he stopped for a while but now I keep getting called at like 3am on a withheld number, no one says anything but its scary, how can I Stop it!

tell uhm your gana call the police and have it traced through the phone service

get a new number

Get a new number.

Check out my song!!

I agree, you can get a new number. sorry to ask this, but I'm curious: what did he say in the texts? lol

that was a dangerose thing to do
because there are a lot of sick people out there
this guy might try to meet you, with the intentions of having sex
some guys are even looking for younger guys
you really dont know what kind of person has contacted you
get a new mobile number
this guy already has too much information
dont talk to him
tell him you dont want to talk to him or your not into anything hes talking about
and get a new phone number
because theres no way you can block him

I partially disagree with jazlovestoskate, dont talk to him anymore, no messages, no talking, nothing. you'd just be encouraging him. also, there is something on the computer that if you buy it, you can type in someone's cell number and get their name, and info on the account, so I would change you number as soon as possible.

p.s. slap the back of you friend's head, that was a butthead move, lol. why did she put HER (or his, I don't know, lol) number online?
