Interesting listing.
After reading the add again and this thread, heres a few thoughts.
The lost drone could easily be returned by contacting dji. They know who registered it when bought new. Simple and honest.
What's being done with it, while probably not illegal, is immoral.
Your side stepping the easy correct thing to do, contact dji, return drone.
Then your trying to justify that action by repeating, it's for parts, I dont know if its locked, I didnt check and DONT WANT TO!
Your definitely looking to scam someone.
Just because you list it for parts, doesnt make what your doing right.
Every honest member here probably should visit that add and report it as a scam.
Just my .02.
YMMV.
