When we accepted corruption complaints at the site, complaints rush to system down

When I opened a website that accepts complaints about corruption in China and started accepting complaints, I heard that a large number of complaints were rushing and the system was down.

It is like a joke, but what is the background like?

Details are as below.
China National Preventive Corruption Bureau website, complaints rushing system down International News: AFPBB News

According to this article, it seems that the system went down the day after the website of the National Preventive Corruption Bureau of China opened. It is thought that this is caused by a large amount of complaints being received at the spread of corruption.

Messages sent to the website were content to convey blessing words about the establishment of the National Preventive Corruption Bureau, but only by collecting and analyzing information on corruption behavior, the authority for investigation is not given to the National Preventive Corruption Bureau There seems to be the same degree of messages which give doubts such as "Why will not they have any effect" and "Is there a meaning to set up a preventive bureau?"

In addition, it seems that the website is asked to post in real name, but most of them use pseudonyms, and some say that there was a message written "Please do not retalate".

Does that mean that corruption is inflated so much ...?
