One of the biggest furry art archives has always banned art without much, if any, actual input from the human who created the artpiece. For example, game screenshots are banned almost universally, picture generated art is as well (something like picrew) 3d models aren't, assuming there is posing and such and so on.
It seems a perfectly fine continuation to the existing rules to ban ai generated art.
Also, Art AI can't click on ads, which is probably, ultimately their main concern. If you replace all the monetized users with AI that can't buy things, the economic incentive to keep the website running disappears.
