If I may share a different point of view, I put almost all of my research on Ancestry.com
and I don't care who copies the information or what they do with it. What I find is
that I gain so much more information in return. My view is that I am only responsible for
the information in my tree. It is frustrating if someone takes that information and adds
incorrect data to it but the reason that frustrates me is that I always hate to see
incorrect data. It can mislead and take people down wrong paths. But, I take the view
that is not my problem but the problem of the owner of that tree. It costs me nothing to
put information I have learned on Ancestry and, as stated, I gain so much from it.
I've lost count of the number of people who have contacted me through Ancestry and
that most often leads to great discoveries for both of us. Yes, I'm always amazed on
those rare occasions when I come across a tree filled with obviously incorrect - and even
impossible data. And, I fail to see what pleasure the owner of that tree can be getting
from such research. But, the fact is that it really doesn't affect me. I'm
thrilled with the information I have learned about my ancestors - often with the help of
others - and I happily share it with whomever finds it of value.
