sue them for IP infringement dude. you're sitting on a gold mine with your art, seriously, and you could put a stop to it.

Fun site and your Muse is a near match to Meta's.

Curious, did you come up with the name "Muse" and make the character art ? Or did you and Zuck coincidentally use similar LLM prompts. If Meta's version was AI gen'd they wouldn't be able to copyright it suggesting it's likely human designed. But if that human design is a derivative of your art, which it seems to be, then they wouldn't have copyright either.
