An internet cleansing movement, or antismut campaign launched by the Chinese authority, is sweeping across the internet in recent days. Well-known online service providers such as Google, Baidu,  Tianya (where flesh search engine prospers), MSN China are on the list of crackdown, because they are thought to publish “vulgar, low and obscene content.”
China Internet Illegal Information Reporting Center  (中国互联网违法和不良信息举报中心), under the Internet Society of China , a nominally non-government group released a list of “immoral” websites on 5 Jan, claiming its source as public reports and complaints.
As Danwei accounted :
Each website listed is annotated with either a remark that the website had been given a notice, but didn't take effective action to clean up its content, or that it did not quickly delete newly added vulgar and low content.
On the list, Google is said to have linked to “obscene and pornographic websites”, while Baidu, the most prominent Chinese search engine, is stated to contain “large numbers of low and vulgar photographs”. Meanwhile, Sina , Sohu , Tencent and many more portal websites with a large population of users, didn't escape the harsh prosecution.
Tip: Search obscene keywords, if you know what they are, in Google, and you can get obscene stuff in return. Visit sections like “pretty girls,” “Women and men” in many portal websites, you've also chances to run into these obscene stuff. But undeniable, much content are uploaded by users rather than the website itself.
One day later, on 6, Jan, the administration took measure. Seven departments of the State Council deployed an overwhelming campaign trying to cleanse the internet. The head of the Press Office, Cai Ming-zhang, emphasized on an iron-fist crackdown :
And he went on the censure:
And the war against “vulgar” digs in 9 Jan:
This time, some relatively less influential websites, including MSN China, were put on the list.
The campaign has already claimed victims. Some high-ranked officials in Netease were dismissed , possibly because of putting Zhang Ziyi's Bikini pictures on headline.
Later, all the websites being criticized have posted apology letters. QQ has even shut down its chat room service, and the questioned sections in many websites are now inaccessible.
Now, the internet enterprises had stooped down, giving in to the crackdown. How netizens, who actually uploaded most of the vulgar content, would respond?
On Netease , the opinions mostly favor the crackdown. The leading comment on the new piece writes:
The internet should be a place for information, communication and entertainment.
But look what is going on right now; so many websites are greeting you with nothing but obscene and violent stuff. Google, as a venerable international enterprise, have you fulfilled your duty for the society?
Baidu, as a well-known national enterprise, have you kept yourself up to our expectation?
Suppor  Disapprove 
On the entire comment page, the voice of support takes the upper hand. However, it is not unreasonable to speculate that because Netease has been warned, it actually censured the comments, as it has done, to cater to the authority.
It is not sensible to deny that the websites concerned are influential. Then, what organization on earth is the China Internet Illegal Information Reporting Center , which is so boldly, that it dares to challenge all these internet giants?
Though self-proclaiming to be Non-profit social group, CIS is widely accepted as an official agency, because it has members like Xinhua News, departments of State Council and quite a few telecom service companies (all state-control).
It is ironic that in fact Sohu, Netease, Sina and many other cleansed websites are actually the members of the Society. The fact more or less testifies to the core of it as official because these websites are not likely to target themselves and push the authority for regulation. The most reasonable explanation would be, the one that really speaks is none of them, but the authority.
Blogger Wei Wuhui in It Talks commented  that the campaign is operated wisely.
And after the websites all apologized, seven departments set down the standard to define what “vulgar” is, with totally 13 items. This is not a law.
So this is entirely a cultural movement, without the shadow of government, but a self-regulation action of enterprises to shape a better internet-sphere.
However, not every person stands with the authority.
政治迷 in Tianya ridiculed  the operation :
But we just can't watch websites with our own money- because it is vulgar!
Tit-for-tat, a list made up by netizens also shows up on the internet, pointing against CCTV, the state-control TV station.
And all the ten channel belong to CCTV  are on the list.
No.1 CCTV1 Leaders and officials are always correct.
No.2 CCTV2 Financial crisis is nothing, China is always proud of its achievements.
No.7 CCTV7 Naive military propaganda, violent and brainwashing.
No.10 CCTV10 Fake science, all but made up.
移山愚公 told why Tianya, a popular online Bulletin Board System, is clouded by the so-called vulgar stuff.
不过这也不能怪天涯！关心时政的帖子不让发，天涯靠什么吸引人气? 那就只能靠低俗的帖子了。 靠那些溜须拍马的5毛帖的话，天涯早关门大吉了！！
Is this a pure campaign against immoral and polluting content? Still, many don't believe it to be so simple.
The 13 official items that define what vulgar is, contain these itmes to forbid:
Apparently, it doesn't concern any bit of political content, or openly forbids anything related to “subversion”, an item usually used to prosecute against political activists. But netizens still nose out a touch of implicit intention, because even though the authority deleted the unfavored posts regardless of whether it really has vulgar stuff, nobody can complain.
李国豪， a netizen in Tianya thought:
GFW(GREAT FIREWALL) blog predicts that 2009 would be an uneasy year for internet and media. 
Now, Bullog.cn, a well-known blog service provider site famous for its bold critiques of the authority, has been shut down. Is this antismut campaign foreshadowing a more severe online cleansing?
