So far, I haven’t seen all that many, and the ones that are are very obvious like a very glossy crab at the beach wearing a Santa Claus hat. I definitely have yet to see one that’s undisclosed, let alone actively disguising itself. I also have yet to see someone try using an AI-generated image on Wikipedia. The process of disclaiming generative AI usage is trivialized in the upload process with an obvious checkbox, so the only incentive not to is straight-up lying.

I can’t say how much this will be an issue in the future or what good steps are to finding and eliminating it should it become one.
