I love the note in the "about me" field!
I would name the "unknown father" "Richard Warren's unknown father" to make it explicit at first glance. In that profile's "about me," I would copy & paste the point that "unknown" is not Christopher Warren. I would probably be sarcastic and add something like "it would be a genealogical breakthrough worthy of publication if you are able to name this gentleman."
I have already gotten two new collaborators on this project. Either they just like my profile photo better or the shaming works.
I don't mind if people don't collaborate: just skip over their profiles in the geni search database. It's embarrassing but I don't work for geni public relations, and I've seen some lovingly tended and pruned trees I'd hate to get ugly too.
What I can't stand is multiple copies of profiles on the main tree with no ability to merge them up. And it's not like, in this situation, we're talking quality data or original research. Someone uploads a GEDCOM, doesn't bother to clean it up, and then won't even let someone else help? Gimme a break, like we say in New York.
The authors of the best profiles are also the most willing to share and help. Which is of course the most in keeping with genealogical professionalism.
