5, medical site or a sensitive industry station group operation;
I carefully collected on the K station on various forums, mainly have the following several kinds of speculation:
1, a large number of acquisition or low quality pseudo original content;
2, sending links or links to buy cheat chain operation;
6, Web2.0 site by spam;
4, the website space, such as filing, server stability;
first we look at the Shanghai dragon why forum initiated the vote. The vote is the moderator wolf Shanghai dragon launched, launched soon become hot, the post visit amount has exceeded 2800 of the visits, as I have 324 webmaster position screenshots of the vote, the voting results are as follows, 232 station site was K, accounting for 71.6% of the number of all.
this simple voting data may somewhat one-sided, although also can explain K wide area, but it is still not enough, here through the database to a Shanghai Longfeng vane under our Chinaz, including data (575710 of the total number of data sampling site):K ratio reaches 2.29%, and the average proportion of the previous K station has been only 0.2% points. All of a sudden increase of 10 times, then the site was K range as can be imagined.
