Bypassing that crap is pretty easy. Just go to [url]www.rewebber.com[/url] and enter the web address there. You're proxy will only report that you've been at the Rewebber site. It's not really fast, but if you're worried about Big Brother, it beats nothing.
By the way, I AM Big Brother at my business. I monitor the proxy logs for "violations". It's GREAT blackmail material (just kidding). If some of these guys wives knew what they were downloading . . .
If your site has blocked Rewebber, just do a search for "anonymous proxy" at [url]www.google.com[/url]. It will usually dig up a lot of info about using anon proxies and give you some IP's to try out. Be careful though, you never know who is running those "anonymous" services . . . could be the Feds looking for kiddie porn.
