How did the Chinese whistleblower website www.ibribery.com violate CCP's Internet guidelines to be banned?

I read about this site a few days ago. When I read the article my thoughts were "how in the world does this site think it can stay online?" This was a site that put on the web the corruption the CCP members did. WHAT! Now the people who run the country are CCP members, how can they let a public site show the corruption in their party? This seemed impossible to understand. You let a website show how corrupt the CCP Party is! Well the CCP seen the folly in this and to save their asses they shut this web site down! Think about what was going on, you have to bribe CCP members to get anything. The CCP members run the country. Duh! If you run the country you surely don't want a web site showing how corrupt your party is! If the CCP was serious about enforcing the laws they have on their books then this would have worked. But the CCP is out to get rich and live the good life so this web site had to go!
