In the last Days and Weeks, we get a very large List of SEO-/Spam-URLs with .pl-Domains like this:
Now the Spamer has changed the Server. The Domains linked now to the IP 126.96.36.199 hosted on OVH-System.
We send for the Spam-URLs a X-ARF-Report via spamlinks.blocklist.de to the Abuse-Department to look at the the Spam-URL. We send only a Report, when the Spam-Score is high enough. So, the false-positive rate is under 5%.
We recommd to block the IP in all Firewalls and Gateways.
