Sorry,
The message was cut off
Suddenly in October I had a spike on inbound links from forums and spams sites. Each one had setup hundreds of links.
The links goes to WordPress internal search.
Example:
mysite.com/es/?s=here a very long text related to a pharma search
No humans are visiting those links but I have dozens of bots digging in those links and looking for invalid traffic.
I disavow the links, but looks that I am David fighting against Goliat with a toothpick
How to stop this?
