I don't know about privacy admins, but I'm in that slow process of contacting pms trying to get profiles opened, death dates changed, trusted list access, etc. I suspect most I'll eventually have to file unresponsive manager requests on. I have emailed info@wikitree about some that were orphaned but unavailable to be adopted because of the privacy setting and that worked well if there was no pm. I, too, am coming across them because of working through data doctor suggestions. It's a very slow process -- especially merging them. No good answer here, just commiseration.
