 how is it blacklisted? I'm able to resolve the domains and access the web servers over IP 
 He mentioned anti-virus blacklists, so if you are not running an anti-virus program that subscribes to those lists, everything will work as expected with no errors or warning. 

That's my guess. 
 yeah, first step in not getting into nonsense with windows shit, is not to run windows 
 That's great man! It depends on your DNS, browser, and OS.   Avast Anti-virus flags it, and these security vendors have it as flagged:

Fortinet
Seclookup
CRDF

We put in requests to them to have it removed.
