I've no fuckin' clue on how to help you, bro. Aside from me knowing little to nothing about computers, software and hardware, my parents were the most lenient of all when I was around fifteen. I was going to say hook up a new router every time you use it, you know, when they're sleeping. But it has already been mentioned.
At my school, one guy found an obscure site full of pornographic slideshows that wasn't blocked. Unfortunately, I don't remember the name. Had a lot of ads, though.
Facebook isn't blocked at my school, and people can access it on their phones and iPods because someone leaked the wifi password last year and they never changed it. So that's what people do all the time.
Well in my school board they see it as a valuable learning tool to incorporate social networking into the classroom.
