These links don't say anything about what actually happens in the book Godric, all they say is that some people are leaking information, its perfectly safe. And they are probably talking about the same thing on the radio, I doubt a radio-host is going to leak information out on the radio, its too risky for them to do that.
What you do have to be wary of is online sites, but your tv and radio shouldn't be a problem, they'll probably tell you what sites not to go to.
