> As interpreted by some courts, this language preserves immunity for some editorial changes to third-party content but does not allow a service provider to "materially contribute" to the unlawful information underlying a legal claim. Under the material contribution test, a provider loses immunity if it is responsible for what makes the displayed content illegal.[1]

I'm not a lawyer, but idk that seems pretty clear cut. If you, the provider, run some program which does illegal shit then 230 don't cover your ass.
