To me, any "restrictions" would be about new members understanding and buying into the Ozgolf Proshop mentality on sales to fellow members, and nothing about keeping away any "shonks". The shonks part is always going to be a simple case of buyer beware.
I see a few that seem to think they have struck the "Mother Lode" when they join here, but don't seem to quite understand the 2 way nature of pricing etc here. Quite frankly, if you haven't got a track record of some participation or buy in, then I am very unlikey to deal with you, at any price. So restrictions don't mean a lot too me, and the PM system gets used plenty to bypass restriction anyway I can say with some experience!. The problem is then though how do you question a newbies intentions etc without it being seen as potential bullying by some? I have a background in Fraud/Audit management and a pretty good sense of when someone is legit or not, but I am very hesitant to be a policeman for such things.
