Are their paid boosters on Audiogon?

I've seen it suggested that there are Audiogon members who receive some sort of undisclosed consideration from dealers or manufacturers to promote or denigrate certain products, vendors, etc.? That's an interesting, somewhat discouraging thing if its real. Just wondering what the group thinks of that- is it true, and if so how prevalent is the practice. 

With one notable exception (no longer on the forum) I've never really suspected that, but never gave it much thought.  There are dealers who just happen to have the perfect product whatever the need may be, but the selling is in the open and nothing is disguised. There are those who always recommend the brands they own, but I tend to put that down to human nature- we all tend to believe our choices are the best choices. We are lucky to have the expertise of incredibly talented designers who add a lot and are kind to freely share their vast knowledge with us-something I truly appreciate.

So, I've never really suspected there are paid shills here, but maybe I'm naive. I know there are YouTubers who receive benefits from sellers-some disclose that, but I think a lot don't, which is unfortunate. I hope that doesn't happen here.

Thoughts?
