php blocks black hat SEO search keywords
I will give you a method and my idea
The idea is like this. Most of the big guys who want to do this have to leave their QQ or phone number
Then I will match the rules inside, find out the numbers in the search, and then judge the length of the number string, and then judge whether it is a junk search
Provide the code:
