If you actually look into the history of the domains linked to "Josef Bakhovsky" and registered with Namecheap you can see they've got put on serverHold
A lot of registrars don't deal with abuse at all and simply say "report it to the hosting company", example here (domain in question was a Redline Stealer C2):
> Please, be aware that we, as a domain-only provider and not providing any content, hosting or e-mail services, are not in a position to judge the content of a website. For that reason, our normal procedure is that we inform our reseller and the domain holder, but will not suspend the domain names without an official WIPO decision or court order.
And an example from the article, NameSilo didn't take the domains down even after talking to Krebs?
