Since this year gametracker.com is ranking over 1000 fake cs 1.6 servers that deserve to be banned but admins of gametracker.com are to lazy and no one cares . This servers and the ips of that one who add them deserve to be banned . Go to cs 1.6 servers and look on page 1 . there are 5 fake servers , on page 2 10 fake servers , on page 3 more fake servers . The owners with normal server can not rank their servers because of this fake servers.

It's not possible to ban the attacker permanently. Besides adding servers aren't violating any rules here, but fake servers will definitely get de-ranked sooner or later.

Reported servers are reviewed and de-ranked manually, so with the amount of reports going on, I think the admin is tired. Solutions to control this situation was suggested before but still no action for some reason.

Even Steam themselves have no proper solution for this yet;
