I use facebook daily. Today, every TOR exit server I try is blocked, regardless of the country. In the years I've used TOR this way, I've never seen any TOR exit server blocked. Facebook says: Access Restricted (Bad IP) - and has a form to complain if you think it's a mistake.
Any suggestions? I use wi-fi hotspots, and I want my connections enctrypted so they don't get hijacked. The free proxy servers aren't safe, and they don't plug holes like TOR does (other things making connections besides 80/443 browser requests). The webproxies aren't safe, because you go through their url, so they could steal your passwords.
