I had no way to blog the dynamically generate URL:
This plugin gave me a valid way to do it and then to protect my website.
crwdcntrl.net used to make many other redirects 302 to other external domains for tracking.
I changed all the files of my websites without finding the origin of this URL.
No malware scan service has marked them as a problem. Even google said that my website was ok. But these URLs were always there.
I added in the blacklist the domain: crwdcntrl.net
Now, those rules are no more there.
Thank you very much, WP DoNoTrack.
I have found WP DoNoTrack from this post: http://wordpress.stackexchange.com/questions/184708/finding-and-removing-unnecessary-redirects
