There always needs to be an uncensored option, but it doesn't have to be the same option most people use day to day. One region's "accountable group of people" is another region's authoritarian police state.

Tor isn't just used by CSAM creators and distributors, but also journalists, resistance fighters, and refugees. The only way it works is if regular traffic is mixed with sensitive traffic, otherwise there are methods to uncover the source of sensitive traffic.

If you run a relay, you will be transmitting encrypted CSAM, but you'll also be transmitting journalist correspondence with sensitive sources, coordination with refugees from brutal regimes, etc. You can't really pick and choose, and that's the whole point and why it can be so useful to people in danger.

I don't think lemmy or ActivityPub should tolerate CSAM, so I'm not implying that censorship is always bad, only that there needs to be an uncensored channel available.
