no-ptr.as20860.net Comment Spammer: Research, Ban

no-ptr.as20860.net is a dual Ip spammer with a twist. The originating IP hostname lookup returns three IPs! You’ll need to ban all three, but there’s a lot more. They use IOMart, GB as their ISP.

It seems like this hostname also morphs to numerous IP addresses, making them difficult to track down.

Observation:
no-ptr.as20860.net hostname lookup 62.128.193.135 84.22.161.172 50.97.43.3

Method:
no-ptr.as20860.net not only uses the dual ip spammer strategy, but also changes its host name through many ip addresses, making it double difficult to ban.
