owning artworks (material) and scan them (sort of a service) must be departed.
watermarking doesn't refer to the material aspect, but to the service. It just shows where it comes from. And i agree 100% with bippym, upside is that more people come to see HOL.
What allow us to do what we are doing with games, so that the games owners don't pursue us, is that we don't make money with their properties, in the contrary, we would be pursued or forced to close.
you bet all this apply to people trying to steal the work done to sell.
Which is not allowed by legal holders ; Watermarking is even maybe protecting us from owners which could ask removal of box scans.
