Example: Mallory sitting in the United States likes to prepare
a list (without my consent) and published on a U.S. site,
so that like SKS key server dumps the whole world can
obtain a list of all openpgpkey subdomains. So far so good.

Mr 'edge case' Stefan knows this and counterstrikes with
his domain radio-eriwan.su (which I own) and set's up for
Mr Mallory a WKD direct-method dir with n dummy keys.

Good luck Mr Mallory figuring out which domains have real
OpenPGP users keys hosted and which not.

Best regards
