"I hate block lists... maybe because I have been on the 'wrong end' of them in the past. But after careful consideration, we do recommend blocking traffic from these two netblocks:
InterCage Inc.: 69.50.160.0/19 (69.50.160.0 - 69.50.191.255)
Inhoster: 85.255.112.0/20 (85.255.112.0 - 85.255.127.255)
The list may be updated later. We do not expect to make this a "regular feature". But at this time we find that it is necessary to point out these particular two netblocks.
They have been associated with a number of high profile criminal activities in the past. A good number of WMF exploits use name servers or other resources in these netblocks. They have been non responsive to current and past requests to remove malicious content."
