I have privacy on all my domains ( a substantial number )..and domain tools still shows ( 10 of them ..I stopped after checking 10 of them*..there are 4 figures ) as private..
Even those with a "feed" ( which are not parked )..and those which are parked ( with a "feed" ), the "feed" suppliers in the two "feed" situations are not the same ..
I can only assume that the situation you find, vis a vis.. your domains, relates to the particular privacy service that you use ..and that used by the domains you were "researching" for over a year ( you may in fact share the same "privacy" services ) ..If I were you ( and also if I were the owners of the domains you are researching ) I would change "privacy" services.
IME "feed" services require "contact details" on site ..they do not require details of actual ownership.
*Better things to do ..and I suspect that many enquiries from the same IP within a short space of time would result in a temporary IP ban..
