Clueless about myspace proxy servers

Am I the only school network administrator that was clueless about myspace proxy servers?

I was feeling very proud of our Netgear Firewall ability to block unwanted sites. Like all the other schools in the country, myspace is at the top of the list.
A much younger techy friend of mine was helping me do updates at our school the other day – and I was showing him that myspace was blocked. Imagine my surprise when he immediately did a google search of :”netgear firewall myspace” and came up with literally hundreds of hits for proxy servers that go around your firewall. If this young man knew – what about the rest the kids in the country?

Has anyone else encountered this? What did you do about it?
