Maybe they could add a 'bad data bot' also, something that validates dates in existing profiles and flags things like for example: dead mother, dead father, mother younger than 10 or older than 50, father younger than 10 or older than 70, siblings less than 1 year apart, etc, There's lots of them out there, mostly the original imported data was bad, and it would go a long way towards a higher quality of genealogical data even without accompanying sources.
