No, it's not. csam is illegal and so is revenge porn, the platform could even be in favor of csam and revenge porn and they'd still need to follow the law.
Ok, I suppose if the takedown was only ever used to enforce the law, then there’s no editorial oversight. But that isn’t any major platform, past or present. Even 4chan is moderated.
“You’ll take down CSAM but not spam/incitement to violence/revenge porn!?”
Further, user reporting as your only form of detection doesn’t scale well or protect your reputation.
