Prevent priviliges to accounts who make continued abuse
When someone makes repeated and continual changes to people or families that are reported as abuse, revoke the perpetrator's ability to change or add things to families/individuals.
This is a public and global site that should revoke the privilege that people have to make changes when abused can have lasting effects on people.
Example: A person is adopted and never knew their biological family members in their lifetime, do not allow people to make fraudulent family trees using that person's adopted family.
My father was adopted and his biological family decided to usurp my father's (adopted) mother and his non-biological siblings into a family tree.
I was told to just continue making changes when they show up. Allow people to block changes from being made on their deceased parents when no changes should be made, especially when not authorized by the recently deceased's next of kin.
