It is no different than the other news sources that ask us not post from there sites. It is JR's decision not to fight with them.
I can understand not posting from their sites, but to not even pass along a "link" to someone? Guess folks have to have a secret password? sheesh! Yes, it is JR's decision and I totally respect that. However, I do NOT respect websites that act as if they are part of a secret society when anyone and everyone in the entire world can find them online. Dumb, plain dumb, IMHO.
