Is there a way to unlink a memorial on Find A Grave?

I created a memorial of a relative and someone has linked a memorial of theirs to it claiming it is a child of my relative but the person is not actually related. I tried to get them to unlink theirs but they wouldn't. I wanted to contact Find A Grave saw no email address for that particular issue. If I delete mine and create a new one can I stop memorials from being linked?

They could be an actual ill-gotten relative. A relative that maybe shouldn't be with a negative history with the rest of your family.
