I don't think you can. Anyone could build a service that crawls the internet, finds 1m domains, and quickly checks them against your list of hashes, and they'd then have a (very accurate!) list of exactly which domains are offering CSAM.... they could even build a website that just links to all the domains!!

Yes, anyone can do that, but that's on them. They have to get the domains from elsewhere and so that is then their fault/responsibility.
I don't know the exact rules and wording around this though, it really depends on specifics
