Using AI Art for Ads: Yay or Nay?

Hello everyone!

I'm preparing to post on Royal Road, possibly next month. One thing I've noticed here and in other subreddits is that many people dislike AI art. However, I've also seen many ads that clearly use it, yet they have lots of followers and a steady income.

I’d like to know if you specifically dislike ads that use AI art. I want to get everything right for my first launch. For my book cover, I’m fortunate that my wife will be drawing it, but what’s the general sentiment on using AI art for small ads?

Thanks!
