The Citizen Lab has a new anti-censorware guide, "Everyone's Guide to By-Passing Internet Censorship for Citizens Worldwide." The 31-page PDF covers a lot of ground, with material for anti-censorware activists and users, and is very handsomely put together.
Circumvention and anonymity are different. Anony-
mous systems protect your identity from the website
you are connecting to and from the anonymity system
itself. They can be used for circumvention, but are
not designed for this purpose and thus can easily be
blocked. Circumvention systems are designed to get
around blocking but do not protect your identity from
the circumvention provider.
Do not mistake open public proxies for anonymous
systems – they are not. Although they may not ask for
personal information, they can view and record the
location of the computer from which you are connect-
ing and all of the websites you visit through them.
Commercial services which advertize anonymous surfing
may still record your connection information and the
websites you visit. Make sure you fully understand the
terms and conditions of their use.
