App publisher steals picrews and runs them through AI

I'm not sure if this allowed or where to put it, or even if anything can be done, but I keep getting ads for apps by this same dev/publisher that all just seem to be stolen frlm different picrews (maybe other character creators), some ran through AI (really obvious, especially with the Nuggts one). They're all early access. I don't know if the creators can do anything about it, or if it's a big deal, just thought it'd be good to spread.
