If Ancestry had less of these spurious entries, would they have as many members as they have? I do not think so. The spurious entries makes the public think that Genealogy is easy, and tracing their ancestors is a cheap hobby. It's only when the curious starts taking tracing ancestors seriously, they find that it's not so easy, and can be quite expensive in time spent and financial costs. That is why, you see so many small public trees which have been suddenly left/dropped for some time. But Ancestry has had the subscriptions' so it's doubtful that they will change things. The same reasons seems to go for the "Newer" DNA side. How many accurate results can actually show direct links between family members or localised origins?
