I found myself posted on a public tree. I am obviously still alive. I sent a message to the tree owner............no reply, no action. I called Ancestry to ask that it be removed, and I was told that they do not, under any circumstances, make any changes to member's trees. I said, 'even if the tree is violating an Ancestry policy?', and they repeated, 'we do not make any changes to any member's trees, ever'.
