Prior to about 2007, it was easy to find a proxy site and use it to get around Internet blockers at school and work. But Internet filtering companies have gotten more adept at finding and blocking new proxy sites, so that most publicly known proxies have been blocked almost since they were first released.
The next step was for proxy webmasters to start creating proxy mailing lists, where users could sign up to receive a new proxy every day. Since most Web filtering programs only update their lists once per day at the most, this means that the daily proxies would usually work, even if the blocking companies would block them the next day. Unfortunately more blocking companies like Websense have started releasing censoring programs that update their blocked-site database several times per day, so that even most proxy-a-day mailing lists are not as effective any more.
The solution is a proxy mailing list like our Circumventor list, which mails out different proxies to different subsets of the list. Most proxy mailing lists are hosted with services like Google Groups, which require the list owner to send the same message to everyone on the list, which means it's blocked almost as soon as people receive it. We run our own list and send different proxies to different users, several times per week, so that the latest proxies are almost always unblocked.
We have over 230,000 users as of January 2010 who use our proxies to get around everything from school and workplace filters in the United States, to national government filters in countries like China and Iran.
