Topic caught my attention but a few issues stand out after reading:
#1) Brand new-bie user won't take escrow and most buyers must pay first.
#2) Others might be able to pay upon receipt of tracking number (not item) which is meaningless because it shows nothing other than something was shipped which could be an empty box or a bag of rocks.
Sounds like it COULD BE a scam but of course that fact can NOT be proven until someone gets sucked into buying.
A vouch based on a description of how it is obtained is also meaningless because nothing is proven until delivery.
I might be willing to give it a try if a trusted escrow is used and if payment is not released until item is in my hand.
I meant I'd take a vouch one if he can verify where they come from. Receipt of stolen merchandise is a felony (depending on value, otherwise misdemeanor), so free or not, if they're illegal, you're stupid to accept one.
