I've never been asked for an appraisal by an honest buyer.
It's pointless - the market value is what the buyer will pay (if it is acceptable to you). If the buyer is unsure of their valuation, that's their problem.
When buying property/real estate it's up to the buyer to get an appraisal if they want it. Not a seller's cost. Same for domains.
The scam normally does have a "selection" of appraisal companies, some or all of which are connected with the "buyer". Maybe you pick the one legit company in the list of appraisal companies. The scammer don't make money this time, but on average they probably get enough return to continue with the spam/scam.
Either way, the chances of them actually following through with a purchase can't be very high (close to zero I'd say).
