It’s pedophillic because it’s sexual images of children; fake or not does not change that. Drawn images of child pornography are still pedophillic.

The more important question is, is it CSAM? Whether drawn images that represent no real child are or not depends on the legal jurisdiction. Should drawn and AI generated child porn be legal or banned? I think the actual answer to that would require significant research into whether its existence acts as an outlet to prevent pedophiles from harming actual children, or whether it encourages their proclivities and makes them more likely to hurt actual children.

Preventing harm to children should be the goal, but actual research of the effects of simulated child porn vis-a-vis pedophiles harming actual children is as unlikely to happen as any other research into pedophilia
