It is well known that online content providers in China have to follow censorship instructions from various government authorities. However, with the rise of private public relation company, there is an increasing censorship pressure from the private sector. Some of them pay the websites to delete content, some retreat to hacking.

On January 26 2011, Bokee.com published an open letter to its users informing them that the website was hacked after they had refused to delete an article. The hacker contacted Bokee.com via QQ chat on 25 of January and demanded the website to delete an open letter posted on August 16 2006 written by two professors from Xiamen University Accounting Department accusing the department head, Chen Hanwen, for academic corruption. Below is a translation of conversation in the QQ chat room:

So you can't delete the post for me, right?

My only choice is to create a shield.

Judge: 12:25:36
If your website has function problem, contact me.

I have created a shield for data transfer. It will probably affect your website's function. If you delete the article for me, I will remove the shield.

The attack went on from 1pm to 6pm on 25 of January. It is a mixture of DDos and SYN attack with fake IPs. BlogChina has reported the case to local police.

According to Baidu search result, the article has been circulated in many websites, but most of the posts have been deleted. Bokee.com and XYS.org remain the only two exceptions for keeping the content online.
