When I revisit profiles of which I am the sole manager and which I have made private, I often find that
(a) the profile has been made public or
(b) a stranger appears as co-manager or
(c) correct information has been replaced by errors.
All this happens without me being informed and consulted. Both with regard to privacy and the accuracy of information, I find this totally unacceptable. It should not be possible to make any changes to a profile or to add oneself as co-manager without the consent of all manager(s). It should also not be possible to make the profile of a living person public (with the possible exception of well-known public figures).
