I wouldn't worry about it too much. To be honest i've done it through ebay twice and they seemed to be legit. I used someone with 100% feedback and tons of sales, even checked the pins on some website that shows you how to tell which are real and which are scrappers. Some people really take the pin trading seriously and are true collectors so they don't like the non legit pins to get put into the system but to be honest from what i've seen those people are out for specific pins which are limited sets, cast lanyard sets and all sorts of other stuff you would never get from an ebay seller so I don't think it really effects them in teh long run (i'm sure i'll get flamed for that comment). My son could have a book full of scrappers for all we know, if he does it doesn't make a difference to him. Have fun trading! My one piece of advice regarding the pins is this, try to go with a theme once you are in the parks. My son did this and was searching for a kermit pin to fill his set and it took all trip to find it. We literally found it at the one disney shop that is in the dolphin when I was checking out of the hotel. It was a big event.
