Which Lemmy/Piefed instances have taken a stand against AI training on users’ posts?

Basically the title. If someone can point me to a list of Lemmy and/or Piefed instances, that would be great! I’m looking for instances that forbid training AI on posts, use some kind of technology that makes AI training harder, or have at least promised to never train AI on users’ posts themselves. Or if you’re on an instance that has taken a stance like that, I’d love to hear about it.
