What happens to perpetrators is irrelevant to the node operator, as once said content passed through consensus rules it has to be stored and shared, unless the node opts out of the network altogether, or in some way avoids part of the chain by running pruned. As far as I know, there is no pruned way to avoid csam with a pruned node as it is more about which blocks when, not content. And neither should someone who wants to run a full archive node have to comply with such things. I’m not a fed, and we’re not talking AML. It’s a fundamental difference between free speech and expectations to host and share things that are counter-productive to our species and to knowingly do so.
