media - Jiefang Daily banned as news source?

CDT translates this rather strange list of Chinese media being banned bij the Beijing Municipal propaganda officials. Part of the piece:

We understand that the current limits on copying news are not easy to implement, but before we find better solutions, please cooperate with us. We will also keep guard for you, and penalize each of those sites that we find fail to follow the rules.

Now the list includes very, very official papers like the Jiefang Daily from Shanghai, the daily of the Shanghai Communist Party. I got the strong feeling that somebody is playing a practical joke here.
