I remember getting a little hot when someone took my dad and my grandfather. I don't care so much about the distant relatives, but I really don't care to have my dad stuck on some stranger's tree. It's just, well...creepy. I did contact this person and finally they removed him (after multiple messages). So far, so good as I haven't seen him attached to anyone else's tree. I guess he was removed before a clickophile found him.
My Aunt Bea was not so fortunate. My trees are private now, for this reason.
