I'm curious what the basis for this statement is. Do you have
statistics?
No statistics. I am repeating comments I have heard from
administrators at the meeting. When perhaps a fraction of a percent
of non-abusive domains publish these records, saying 'many' would of
course be like describing the fleas of a flea. It was not clear if
this was the result of some type of reputation response due to abuse
of the '?', which effectively says 'never mind'. If you feel this to
be in error then '?'. It does follow that I had expected and would
be a natural response when seeing this as means to prevent the
exploit of a neutral result.
