In my scheme, people will have the very personal reason of not wanting to let down the person who gave them the file (as I explained, for instance, in post #366; please note that it's not necessary that the potential uploader cares about the original file buyer).
This is a key difference. It means that my social DRM system features what I called a "distributed damping system" based on social links between people.
It is no difference at all if the original buyer is uploading the file.
And if someone has no moral issues with uploading a file for thousands of people to download, why would they have an issue with removing watermarking from a file in order to do that? Once removed, they can't get the original buyer in trouble.
