" in order mediate in any disputes - they cannot be seen to be part of it?"

piffle! That is just splitting hairs. We don't HAVE any totally objective, non-interested parties who are paid to 'mediate'. If we tried, they'd have to READ all the threads regularly in order to comprehend the issues, and how long would it take ANYONE to wade thru this morass of threads to ascertain who said what and who should be censured?!
   The only people capable of dealing with these debates at all are some of the ones who are affected, AND who are trusted by the owner and respected by a majority of the parties.
