If there is a problem of awareness inside China due to censorship, then large numbers of websites around the world posting something commemorating Tienanmen Square on each anniversary -- if only a standardized graphic linking to more information -- could make a difference. Usually, actions such as signing an online petition or posing a graphic mean little, but it could help solve this specific problem. The participating websites wouldn't have to post much information; they only need to prompt people to ask questions and find answers. If the Chinese government blocked all the websites posting the commemoration, it would attract more attention and legitimize the issue's importance (otherwise why would the government make such an effort). (It would be interesting to see which companies and people with business in China would participate.)
