does your school have an approved DET isp provider? if so, lean on them 
heavily to get their act together and keep their filter lists up 2 date.
If your school provides its own internet services [and manages its own 
proxy server] then you'll need to get a hold of a long list of proxy 
bypass servers and update them frequently on a blocked basis whether in 
ISA or SQUID or whatever solution you use.

Here's a link to techie's file in a govt. sec. school list of known 
proxy bypass servers;

send the tech. bods at that school a thankyou...
