I'm answering from a bit of a different angle, but I'll still give my opinion since I own the site
It actually depends on the element and/or paper. Some are so obviously AI - they don't get my support. Things like extra fingers/toes, weirdly shaped flower petals or leaves that aren't connected like they naturally would be or any other unnatural element that just looks wrong. Lol, we've all seen the extra hand in the weird place, etc.
I've dabbled a bit with AI, and I find that it pushes me to be a bit more creative, but it's very frustrating for me. I'm just not very good with AI prompts, and don't have the time to work on it. So, I'd rather buy CU from someone that has really learned to use it in a positive way....and some of our designers are REALLY GOOD with AI.
If a CU designer offers products created with AI, I prefer that they give it their own touch or their style. I like seeing something and knowing who created it, whether he/she used AI for part of it or not.
I do worry where AI is going in an already shrinking hobby. I hope our customers will continue to support our designers, as we have some of the most talented ladies in the digi industry on our team!
