Kinda like how they handle false copyright claims by not taking down the content, oh wait ... that seems a similar situation in that acting on false content takedown requests doesn't get them [much/any] revenue and provides a relational hit to users (but pleases some huge customers, no doubt).

Someone has given a credible mechanism for take down, report it as fraudulent. I find it highly likely that if you have a paying B2B relationship - eg you're a high paying advertising client, that you'd be able to report "frauds" and get immediate action.

But if course I've wouldn't know, and presumably Google would have NDAs for businesses in any special access (it would also be detrimental to the business to disclose it and risk losing the special access).

All we've really got is our TrustRank RTM on our part experiences with Google and similar corps.
