Even if it’s just a recommendation on a different group in which to ask the question, I’m curious how Lemmy combats criminal activity and content like human trafficking, smuggling, terrorism, etc?
Is it just a matter of each node bans users when they identify a crime, and/or problematic nodes are defederated if they tolerate it?
And if defederated, does that mean each node has to individually choose to defederate from the one allowing criminal activity?
There are reporting features. In most jurisdictions, accepting reports and acting on them is plenty sufficient to meet any legal obligations, and many consider scanning every message unnecessarily invasive.
I don’t, and literally everything on here is public, so it’s not identical, but look at the response to Apple’s proposed (otherwise privacy preserving) CSAM scanning on cloud photo backups.
