Tricky one this Jimmy.
I've bought and sold lots on oOple - but not really used the trader feedback - i've never asked for it and only recently saw someone had posted a bit for me. Maybe it's just me, but for occasional seller (like me) - I have very little feedback even though i've sold loads.
High post count is good - or maybe you just need to be voted 'trusted' by other members - start by 'trusting' the main guys you know Jimmy and then they can trust others - like a pyramid scheme
No worries paying the trader fee - but as mentioned it's not really a deterrent unless you are asking for real proof of identity which will be a huge job to manage / process.
Bloody nightmare - if people want to scam folk they will always find a way mate
