Well, there are lots of scams while doing this trade, but when it comes to comes to drone, I have a big concern.....
As we know, we can get services from DJI if we know the serial number of drone... so during the transaction, buyers might take photos of serial number(which is kinda noticeable scam)
However, if sellers sell their drone, get an exchange service(telling that it was stolen, etc), the drone will turn into BRICK with PROPS...This is the only reason why I don't buy used drones, Does someone have any ideas to prevent it?

I've bought two used drones.  Both purchases were made in person following a demo flight by the pilot who owned it.  Then I observed him unbind the drone from his account.  I never had any issue with either of those drones but again the purchase was made in person from the actual owner.
