I came across this webpage from the National Genealogical Society entitled "Standards For Sharing Information With Others."
Some highlights that I want to draw attention to about proper behavior of responsible family historians.
inform people who provide information about their families as to the ways it may be used, observing any conditions they impose and respecting any reservations they may express regarding the use of particular items.
require some evidence of consent before assuming that living people are agreeable to further sharing of information about themselves.
convey personal identifying information about living people—like age, home address, occupation or activities—only in ways that those concerned have expressly agreed to
are sensitive to the hurt that revelations of criminal, immoral, bizarre or irresponsible behavior may bring to family members
