It's a new trend for Anonymous that may stick around for a while. Al Jazeera:
On a Twitter account established in late March, Anonymous China listed the websites it said it had hacked over the last several days. They included government bureaus in several Chinese cities, including in Chengdu, a provincial capital in southwest China.
Some of the sites were still blocked on Thursday, with English-language messages shown on how to circumvent government restrictions. In a message left on one of the hacked Chinese sites, cdcbd.gov.cn, a home page for Chengdu's business district, the hackers expressed anger with the Chinese government for restrictions placed on the internet.
"Dear Chinese government, you are not infallible, today websites are hacked, tomorrow it will be your vile regime that will fall," the message read. "So expect us because we do not forgive, never. What you are doing today to your Great People, tomorrow will be inflicted to you," one of the messages read.
