familysearch.org, as data

[Paul W](<https://community.familysearch.org/en/profile/Paul W>)You appear not to have understood the open-edit format of Family Tree before you began participating. No, there is nothing you can do to stop anybody - from close relative to someone of no known relationship whatsoever - from adding names to the branch of the tree to which your ancestors and relatives are added. You do not have your own family tree here (even if it's been just you who has previously added all the details), so nobody needs any permission to amend your work.If other users make errors, you have to correct these yourself, although you should try to contact them in order to query their additions / changes. Hopefully, they will be responsive and you can resolve any differences of opinion.In view of the nature Family Tree, you should always keep your data backed-up in another program that cannot be edited by anybody else. Also, you can download your family tree to the Genealogies section of the FamilySearch website, where it cannot be edited, either.[](<https://community.familysearch.org/en/profile/Chas Howell>)[Chas Howell](<https://community.familysearch.org/en/profile/Chas Howell>)General comment, we cannot "Lock" a tree. We do not have individual trees (other that your private Living area). There is only the one shared tree in FS Family Tree.I started a family tree some long time ago, and forgot about it. Now I get a notification that some unrelated person modified my tree, with unknown names. I did not know that could be done, but I see that FamilySearch must be the only company that allows such a thing. It is not right! and I disagree with this policy. How are you to know the accuracy of that added information without finding the sources and verifying them yourself, or communicating with that person?Therefore, I will combat this by deleting everything with my name and relatives on here and never use FamilySearch again. No business for you, FamilySearch! 😯It is unfortunate that you did not check that Family Tree is an open-edit, community project before you went ahead. Nobody has their own tree and, if others have made inputs to the profiles you created for your relatives, you won't be able to delete "everything with my name and relatives on here". So regardless of whether you choose to visit here again, your relatives' profiles will remain.I would stress I have no connection to FamilySearch but did my "homework" before getting involved with the Family Tree project, so there were no surprises for me when others started to make amendments to my work.
