Just had some more thoughts on this as well.

If Reddit can lure Patreon users, they could also likely protect that content creators data from being shared on the platform. The creator uploads a commissioned drawing for it’s paid users, and then someone tries to copy it and show it in /r/pics. But since reddit has the source image, they could be scanning for identical images by hash, or matching images via AI and then prevent it from being posted outside the community.

It definitely isn’t THAT easy, but it opens up the potential, and being able to tell your users you have tools to help keep it off a prolific platform probably has some merit.
