Yes I also have the same issue, if people keep putting on incorrect information, why keep going surely they see the hints that we would put on, dont they check those either? One wonders.
The other issue I am having is people who have family entered with same town they live in, which happens when the same town is in the USA, they ALWAYS put the USA entry instead, I always Google the name or address to double check new information, it has now taken me over a year to get most of it correct
That came about by me contacting the person who owns the tree taking the time to check their answers if you get one, as so many start on the free one then dont carry on, resulting in confusion and more research to find out more, then that may not be accurate either
Good luck to all with your research
