Sneakme.in works from time to time at my school for some reason they wipe the proxy list every once in a while. Also concealme.com
Mine do... :censored: This guy had his account temporarily disabled for trying to evade the firewall...damn SonicWall! Apparently forums are blocked because they come under ''Web Communications'' - the web is for communications!
Yeah expect pretty much all school filters block that website as it's so popular and contains @ss in it which they filters in my school block automatically :S
