When I was in high school, a bunch of us used Anonymizer to bypass Bess and access blocked sites.
Needless to say, there were a couple instances where the computers were out of order...
The fact is that you make it sound like all you need is to run Anonymizer on a Windows box and you'll be completely safe--when in reality, nothing could be farther from the truth.
I had a Windows laptop crash after using it--one of the things that drove me to Linux to begin with...
Quit talking about your childhood and find some way to crash me. If you think you can, since you said anonymizer didn't help prevent that.
