Would they rely on a simple whois? As a lot of domain names offer private option and it doesn’t show who the owner is.
I’m not entirely sure to be honest. I usually meet up with SEO guys when I can, about 4 years ago, one of the guys was building what I would call a bad neighbourhood. He has setup his own NameServers (private) and on different servers setup legitimate sites, and bad neighbourhoods.
When the bad neighbourhoods got pulled from the SERPs.. so did the legitimate sites. The only thing in common, was the nameservers.
