An IT team being good doesn't have anything to do with new web proxies being released that are not blocked yet. No IT team at any school is out there blocking new web proxies on a daily basis. It wouldn't be a realistic task to even think of pursuing. Trust me... they aren't stopping proxies unless they have your network so insanely Nazi'fied that the ONLY sites you CAN access are ones they manually added to a "safe list" in which case 99% of the web is blocked. Very unlikely that's the case though. They're probably going by a block list that has to be added to.

The idea of getting caught and running into trouble, however, is probably a very real threat and I certainly wouldn't want you running into any issues because of us. Hopefully you'll find a method that doesn't draw attention to you... but then again didn't you say you'd be in a dorm room and wouldn't there be a computer or your own personal laptop or something, so as to not have somebody literally catch/see you on the site?
