Who says I don't
But it'd be a pain in the ass to patrol a list of who can or can't have/use all of these things that are not blacklisted.
Take hotlinking - what do I care if a webmaster hotlinks some banners or pics from one domain to another? But I'd have to know that it's their domain & then do a whois to see if they own the other domain & then keep a list of what domains they own & reference that each time I see hotlinking and......fuck it. No hotlinking
