Loretta, following on what Leandra has said, I wouldn't encourage you to file an MIR based on FaG. After all, there are way worse reasons, including unsourced family trees and nothing at all, that people use to add profiles.
Some FaG memorials do include biographical information, and when people are buried together in a family plot, it does provide some indication that they are family.
If the person is overriding correct information you have on profiles, that is a reason to protest, whether or not they cite FaG.
