In this issue, the editor will bring you about the alternative ways to prevent SPAM. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

We know that SPAM exists largely because a handful of search engines (such as Baidu) do not support the rel= "nofollow" attribute. Not supporting nofollow means that search engines account for all the times a link appears on the Internet, and the more the number, the higher the ranking of links on the search engine. This is the fundamental purpose of Spammer's insistence on spreading Spam.

The only way for Blog to really put an end to SPAM is to start with the links of the commentators. At present, there are two practices on the Internet:

1. Remove the commentator's link, and it's over; 2. Add a jump page before the link to actively fix the loopholes in "a handful of" search engines.

The shortcomings of the first method are obvious, and it is impossible for most people to do so; the second method is reasonable, but it is troublesome to operate, and there is a QueryStrings in the address, which is bad for SEO.

In fact, the second method can be modified in a different way, which does not affect SEO and does not need to write jump pages.
