When copies are super abundant, they become worthless. Instead, stuff that can’t be copied becomes scarce and valuable. ~ Kevin Kelly
If you are selling information products, you might want to consider only shipping physically printed products. They are harder to copy, have a greater perceived value, and what’s even better is that, at the same time it makes you unique in today’s all-digital world.
To be aware of what is a rip-off and what is original.
Allow people to publish rip-offs (and who did the rip off) they find and show the original. This might help people stay away from rip-offs, show them and give credit to the original, and shame the one(s) doing the rip offs.
