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?
It is up to the home instance of the user, and problematic nodes are defederated.
Instances can choose to operate either blacklist or whitelist mode. Most are on blacklist mode, where new instances federate automatically.
It seems like a potential scalability issue, and a lot of work. Props to the administrators who deal with this right now.
