Good on you for trying to get around it. That kind of curiosity is a great way to develop your lateral thinking skills. You didn’t ask for a lecture and people giving you one should go back to stack overflow comments. If you want to take the risks of it, that is up to you and you are likely to fuck up. That being said, you aren’t the only person likely go get in trouble if you fuck up and, unlike you, IT will depend on their job financially. If you do it well enough and make sure you don’t get caught by someone seeing your screen or blagging around the school that you did it, that won’t be an issue.
IT departments also read comments in threads like this to find the current trends of how students are trying to get around their web blockers so keep in mind that you will need to keep your skills up to date.

This is yet more “one rule for them and one rule for everyone else” from leaches that are desperate to profit from the work of others and punish anyone who won’t pay into their state-enforced protection racket.
