I don't really get what you're trying to do at the moment, trying to impress us that you nearly got expelled from a school for using a proxy. The blocker, however annoying, is in place so that students don't go on any malicious websites etc, it's your own fault if you get expelled, don't try and find sympathy.
Sure, you may know more than that
ICT teacher, but who cares? It's his job and you're humiliating him in front of his colleagues, how do you think he feels that a 15 year old is doing this to him? Just stop being an arse and face the consequences, promise to them that you'll never do it again.
Also, if it's your laptop, they have no right taking it from you for any longer than a day, and that is the law
