> If you are willing to sell, the interested buyer has no way to learn that short of a cold email to a WHOIS contact that privacy redaction has probably removed.
Has everybody forgotten about well-known email alias addresses? Inquiries about the hostname itself would be (among other things) exactly what `hostmaster@domain` was intended as a point-of-contact for. No need for a working WHOIS service, let alone a non-privacy-redacted WHOIS record.
I've recently bought many domains (1000+ over the last year). A few of them (the more valuable ones) all had TXT records for `@` (the root) that had for-sale info. This new record is just a TXT record anyway, proving the point that the interested buyer can quite easily learn of a domain for sale with existing mechanisms.
Also, for domains that are just "parked", not in current use, obviously the parking page can just have a for-sale banner. This is exceedingly common.

Laughable misrepresentation.
