The other solution is to stop publishing biographies
of living
persons, or at least to offer subjects deletion on request.
By hosting living bios, and by inviting anyone in the world to edit
them, we're encouraging bad editing in a quantity we have no hope of
controlling.
That would leave a major hole in our coverage. There has been talk of
deleting articles about people that are only slightly notable at their
request, but that just results in arbitrary definitions of how notable
you have to be to not be allowed to have your article removed.
