Yeah but the package is postmarked by an impartial 3rd party, you're using the tracking number to prove you sent something, if they show that postmark and that the package is not tampered with, then they open it and a brick is inside. It proves you sent a brick.
You mean the buyer also making a video when opening, right?
It's a good point.
If the seller seals the package the right way it can be hard to fake on video.
Not bulletproof though...
Do people here follow these guidelines?
I do. There are a lot of horrid and cruel people in this world that will try and cheat & steal their way through life. I always (now) take the proper measures to deter this type of behavior.
