whats up with posting loads on forum?

I don't really care that loads get posted on forum, but I pisses me off to click on what is supposed to be free on forum to get a message that says I have to pay for premium service to view the post. I haven't pulled a hopper in 2 years. So the information is of no concern to me. It's the idea that it's on forum and requires a premium to view it, plus
it says right here in big red letters Do not post want adds or for sale adds that's what classified section is for.
