I think this says more about the Moderator of r/Art than the devaluing of art.

The artist deserves an apology from the anonymous Mod and reinstated in the sub.

The fact that generative art is being called out is because it can be produced with nothing more than a few prompts.

If generative art wants to be taken seriously, it needs to be presented transparently, as being produced by an algorithm - not touted as human-created. But people will - and do - take credit for things that they have not made.

The real issue here is the drive to monetise generative art for corporations and individuals who see a cheap and easy way to make a profit.
