CSAM is still distributed on the clearnet too... why isn't there a "solution" for that too?
So far the only solutions people seem to have come up with is mass surveillance, and that's not an option.
Did you know that the Tor Project allows exit nodes to filter based on the clear internet IP. So filtering is ok.
However, if a relay refuses to service an onion site directory look up, it will be banned by the Directory Authority. They could allow this today. But they don’t. That’s the simple solution. No surveillance. Not back door. No less privacy for everyone else.
edit: This is easy to confirm. I’m not asking anyone to trust me.

"These authorities are operated by trusted organizations or individuals with a strong commitment to the principles of privacy, security, and network neutrality."
Emphasis on neutrality... it's not the job of network operators to police the sites people can and can't access, this is exactly why many people use Tor in the first place.

Speaking for onion services... no, they cannot, because the entire design of the tor network prevents this in the first place. No relay in the circuit knows the final destination because it is encrypted multiple times (like an onion) and each hop can only see where it needs to go next, not what the destination is.
That's simply not true. Exit operators who intentionally block websites are flagged as bad relays.

The documents you referred to just say you need to honor your own exit policy.
Specifically, it would be easy to add code to hsdir functionality to deny requests for onion sites that are known to be related to csam. Those sites could be announced by the DAs as part of the consensus file, for example. The Tor Project currently lets exit nodes filter by IP address as long as they announce that in their config; this new functionality is of the same kind in the abstract. This change would not be a backdoor. It’s not going to weaken the privacy of anyone using Tor.
The current setup is an extremist position that children who have been abused are not deserving of privacy. It’s a position that all information deserves to be free even if that information is very clearly harmful to others and has no positive benefit to society. One can have that opinion but you won’t find many (outside of this thread) that agree.
