There's a procedure....first place a comment on the profile. Then ask to be added to the trusted list and send a message to the PM. If you don't get a response in 7 days, you can file a UPM - Unresponsive Profile Manager request. You'll find this in the Genealogy tools section of every profile. This will take a day or two, and then the profile will be orphaned. We do this all the time working on Unknown profiles.It seems like a hassle, but it protects everyone and assures that the PM really isn't active or paying attention, no matter what their contribution feed says.
