While his message is strong, I doubt he values individual readers very significantly. He runs multiple mailing lists which recycles his content between them, all of his output he turns into a commodity to be sold or leveraged to further his interests. He maximizes for the best results with the least amount of effort to achieve them. As for the content he's generated, his message hasn't changed in a long time and I haven't seen too many new thoughts from him in a while, though I've stopped paying attention, too. I'm not knocking his strategy. He's an excellent business man who has worked the 20-something niche for all its worth. I would guess he's finding that doesn't pay the bills and is simply broadcasting his message for a different demographic (seemingly ANY demographic that will listen).
Your point is appropriate, but to answer your question the policy is very ad hoc. Those with a personal agenda get noticed and drowned out by the community. It's up to the community to decide.
Regardless of previous success, I think we can appreciate someone who is still excited by a new opportunity and sharing his content for anyone who might find value and/or support his quality content. Many financial fundamentals have been taught before, but can be repackaged and interesting and valuable to readers, especially those who haven't read his book (which I haven't). Like Mike says here, some overly promotional agendas get drowned out, but there is also a certain amount of community appreciation for people who just come out and say "this is something I made, what do you think?" Of course, in a social voting system, if people think "wow that sucks" then they downvote the content and leave a "that sucks" comment.
While they aren't addressing the same types of discipline, I'm wondering if this sort of self-fulfilling outlook they describe can be applied to the financial situations you address, or if you can explain where they might be misinformed.

Also, small typo in 8th paragraph - I think you meant to say "extraordinarily".
