I guess I'm at a loss. I am certain I have traded scrappers in the past (before I even knew what a scrapper was) but I will not knowingly trade one in the future.
That said, I don't think you can say with absolute certainty that getting pins for about $1-$2 apiece means they are absolutely scrappers. As I've said before, there are places to get pins cheaply, promos, etc. My DH had a HUGE pin collection from when he was a CM at the
Disney store - we sold them off awhile back and started each auction at 99 cents. They weren't scrappers at all.
So, what is a person to do? No way am I paying $7-$10 per pin and risk my DD trading them with a CM for a scrapper! And even after looking at PinPics and comparing some of the traders we had left over from our last trip, I can't tell with any certainty whether they are or are not "scrappers" - even if a pin has known scrappers in existence, there are still legitimate pins of that design available too.
I guess we either try to find reasonably priced pins on ebay or
DisneyStore and trade them or just be done with trading altogether - which really would be a shame because DD and DH enjoy it greatly.
I guess the only advice I would give folks is NOT to buy directly from Asia. Unfortunately, I have likely been duped by sellers in the good old USA (claiming to live near
DisneyLand or WDW).
ETA: I actually think it would be sad if CM's start refusing to trade based on a suspicion - especially because many people seem to acquire fakes through trading legitimate pins.
