>>80522803I really fucking hate that attitude.
Imagine if you made something so popular that people started making their own art based on them. That's an incredible gift you've given them, your creation resonated enough in their mind and spirit that it inspired them to create. Be proud of that, be proud of yourself and be proud of them. Even if they're making porn of it. ESPECIALLY if they're making porn of it. You made such an impact on them that they actually felt emotionally and sexually attracted to the characters that you created.
Disregarding commerce and the law, your art isn't yours. Once it's out in the world, you can't control what happens to it or what people do with it in their own power.
