Ok i temporary added cnn.com to diversion and it blocked it beautifully.Also, if CNN is already in your browser's DNS cache (looking at you, Firefox) then it will get around Diversion. You'll need to clear your local machine's DNS cache.
I wanted to add a "hosts file" to diversion to process and block. Where do i go to the option to import a file.
For skyneti tried just website1.com website2.com each on a seperate line in a file and it failed
