Carrierzone.com

This is a hosting service with a very strong anti-spam and anti-abuse policy. If they are up to that claim, they should be trusted.

carrierzone.com appears to be a webhosting service. I ran upon the domain count.carrierzone.com in a website with a single file called /count_server/.count.js. I suppose you would have to watch the subdomains since NoScript only looks up the top domain here.
