Pete, the following statement is simply BS.........

"If you believe that the growth of the hobby benefits all collectors, then you should have concern about newcomers being fleeced. these sorts of experiences discourage the growth of the hobby."

In my opinon, what discourages the growth of the hobby is the lack of self learning and desire to learn. Why should I be concerned when the individual who is doing the buying is not concerned. If he/she was they would have done their homework and wouldn't be buying the item in the first place.
