I don't oppose AI-generated images in the slightest. I love them and I genuinely think they will be a very important part of our future. Effectively, it will take more effort to make a living as an artist, especially a mediocre one, because AI is now a decent mediocre artist. It's a stupendous artist for some prompts, too.
However, I can understand that if I can just spit out image after image, there must be a way to "limit" my submission of these images. In that sense, I "get" banning AI-generated images, as a way to stop spam.
I'm in some Discord chats for various things, and they often have a channel where people can post their artwork. Often, people spend weeks or months on a piece of fan art that's related to the Discord topic, or they draw a picture of the "leaders" for fun.
Lately it's been just getting drowned out by people posting ridiculous AI art where they try to get absurd results. It was interesting and fun at first, but after seeing probably as low as 20 of these images I can tell they're all a similar sort of thing.
I feel bad for people posting their art getting drowned out by this, and these aren't even remotely art related groups.
