The prediction that I would "weigh in" is accurate. Thanks, T Stanton!
There has been discussion within the Disproven Existence Project on connections. I personally believe a person who never existed cannot have parents, spouses or children and when such a profile is retained on WikiTree all connections should be severed in the data field, but named and linked in the research notes so the people can understand why the person never existed and what other profiles are involved. However, it is acceptable to retain the connections between non-existent persons, i.e. Mr. Fraud can be connected to Mrs. Fraud and both to Baby Fraud. The critical connection which must be broken is the connection between a non-existent person and a real person.
Project protection can't solve every problem but it does reduce the possibility of adding bad connections, so usually a Disproven Existence Profile is project protected. It can be project protected by any WikiTree project that has an interest in it, and if not, by the Disproven Existence Project.
I just looked at one profile categorized under the Rayon Meyers Tingley fraud. Intentional genealogical frauds are loathsome because they contaminate every person they touch -- if a name of a real person appears in a work by a fraudster, there must be extra care to ensure everything about that real person can be verified, because we know that fake stuff is out there as well. Hence, the real people get categorized as well. The profile I looked at was of Anthony Day, a real person. One thing missing from his profile is an explanation of why he is categorized under the fraud. An explanation that he was named in the fraud, and of anything falsely attributed to him, would be helpful in that profile.
The "Uncertain Existence" template invites further research. Once we've given up on a person and really believe they never existed, they are candidates for Disproven Existence. A key ingredient of getting that label is what I call the "G2G Challenge" -- G2G must be notified of their candidacy ("Disproven Existence Notice") and they only get the category if no research proving their existence has shown up in a week.
I don't think anyone has won Disproven Existence's "G2G challenge" yet. I would consider it the pinnacle of research skills for someone to respond to the G2G Challenge and prove through reliable sources that a candidate for disproven existence actually existed. Some sort of award ought to be in order, perhaps posing for a photo with the WikiTree Team at Rootsweb!
