Not the person you are asking but alternatives I can think of are:

- Configure forums using ranks so that new users can post but nobody will see their post until a moderator approves or other members vouch for them. Some forums already have this capability. It's high maintenance though and shady people will still try to warm up accounts just like they do here at HN.

- Small communities make their sites invite only and password protect the web interface. This is also already a thing but those communities usually stay quite small. Some prefer small communities. quality over quantity, or real friends over bloated "friends" lists which is common on big platforms.

- Move to Tor onion sites so that one has more time to respond to a flagged post. Non tor sites get abused by people running scripts that upload CSAM, then snapshot it despite them being the ones uploading it, automatically submit to registrars, server and CDN providers so the domains and rented infrastructure get cancelled. This pushes everyone onto big centralized sites and I would not be surprised if some of them were people with a vested interest in doing so.

Not really great options but they do exist. Some use these options to stay off the radar being less likely to attract the unstable people or lazy agents trying to inflate their numbers. I suppose now we can add to the list government agencies trying to profiteer of this new law. Gamification of the legal system, as if weaponization of it were not bad enough.
