New form of domain appraisal scam

I've just bought a couple of domains on the aftermarket: AppraisalScam.com & AppraisalScams.com and until I get around to building them properly have set them up as mini-sites on 1plus. While I was setting them up I saw some news items that alerted me to a new variation of the old appraisal scam.

The traditional appraisal scam works by scammers approaching a domain owner and offering a very good price for it. Negotiations continue for a while, and then the buyer "Needs" an appraisal to convince their boss, or for the bank manager, or some suitable excuse.
