Without any connection to this case I want to mention that I am arguing for removing all Curated By names and make Master Profiles a shared responsibility for all curators, making some minimum agreements on what classifies to be a Master Profile and have a contact curators link which gives all curators an option to respond making it easier for a curator to take a break and even quit as a curator.
I often will make a profile MP after merging multiple profiles, and then want to prevent future erroneous merges. These can come up quite frequently, faster than cleanup can be done. After we get a handle on all these duplicates floating around, focus can then be put on cleaning up the ones that were missed along the way.
