In my last year of college our internet was unfiltered, but if you got caught doing something you shouldn't be looking at then be prepared to face the consequences, which I think is fair enough.
Just a note to some of the younger guys really that are still in school, these filters are in place to protect you from the nasty men with the gas masks, and although it may seem fun to try and find a way round these protection meassures, the only people you are harming are really yourselves. I'm sure your parents would really like to know that instead of doing work, your trying to hack MI5 instead from your schools connection.
Also it's not fun for the guys that run your ICT departments either, they have to spend hours sometimes clearing up the mess that you lot leave behind, and they don't want to filter your access either, but at the end of the day when your in school, college whatever if you don't agree with the terms set out in your IT department, then don't use the system, it's as simple as that really.
I'm not exactly a saint myself when I was at school, I tried to find ways around the filtering systems, but you always got caught in the end, it was never worth getting in trouble for either.
When I was in 6th form at school, I used to help run our network, I remember when 1 kid, I forget what he was called managed to infect the entire network with the win32 CIH virus, it took a week to get the system working properly again
Sorry I'll get off my soap box bow, I just find it annoying when I see threads like this.
