CNET allows website links, but not those seeming to be used to promote someone's SEO to increase hits to their own sites. The links should be aimed at information that's helpful in the thread.
I tried to reply to a comment tonight and a red bar came up and said that I was banned from commenting. No email telling me why and the "Find out more" is not helpful at all. I want to know why! I was having a debate with a another poster. I did not "violate" the policy, in my opinion. It was a debate using website links and information.
