With China trying to silence over 30,000 rioters during the weekend, by deleting forum postings and deactivating accounts mentioning the riot,
Chinese bloggers have started using a widget they originally came up in order to
bypass the "Great Firewall of China" by blogging backward, vertically and horizontally :
"So bloggers on forums such as Tianya.cn have taken to posting in formats that China's Internet censors, often employees of commercial Internet service providers, have a hard time automatically detecting. One recent strategy involves online software that flips sentences to read right to left instead of left to right, and vertically instead of horizontally. China's sophisticated censorship regime -- known as the Great Firewall -- can automatically track objectionable phrases. But "the country also has the most experienced and talented group of netizens who always know ways around it," said an editor at Tianya, owned by Hainan Tianya Online Networking Technology Co., who has been responsible for deleting posts about the riot"
An old-school content obfuscation service that they could take advantage of, offers the opportunity to turn a short message into spam or a fake PGP encrypted file, where both parties can easily decode them to the original.
Spammmic is what I have in mind.
