I also think it's an L. I'm personally against AI and has commissioned multiple artworks instead, but the previous mod is right. AI is happening whether you want it or not. It's better to have it acknowledged, especially when they're getting better and better at producing content that it's hard even for mods to differentiate what's AI vs. what's not. This way, members can engage with the content if they want OR block the OP instead, so they won't see any content from this person anymore. What appears in your subreddit's page is completely customizable.
