To his credit, Ramit knows business and finance to a tee, but I question his social marketing savvy. I've been following Ramit's work when his IWTYTBR blog was just starting and his bootcamp programs and Scrooge Strategy mailing lists were not yet released.
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.
