Looking for a duplication

I want to find a guy with many skins to duplicate to my pc aaccount i dont have a ps4. I want to just trade dont really have money to pay you.
contact me here on on skype drg1337 i can do discord as well. dont try scam tricks on me wont work.

I don't think duping is a thing? I don't play pve, but with the framework, i can't see how it would be done without some sort of server sync exploit?
