Need recomendation

Ok, here's the thing.
There's an idiot (popular stereotype, no need to say anything else) who calls my cell to play pranks on me, it's really disturbing. I want to turn this back to him by sending massive anonyomous mails + text msgs. I can think of many ways and softs, but anon always knows the best options. I have to deal with him every day at school, so fighting with him is not a good option knowing he would kick my ass with his hands tied up.

I know how lame/stupid this looks, but it's all I can do.

Thanks a lot anon.

Sorry we need bangbros passwords as the demand is running quite high, 4chan has quite the reputation to live up to as the bangbros password providers
