Chatter Net doesn't offer a solution to spam / unwanted traffic, but maybe it can give tools for people to create their own solutions. The idea is to have a network of servers, and each can enforce their own rules (the simplest of which would be to only accept messages from known users).
To the user, the servers are rather transparent. You can connect to multiple servers at once, and you can connect to different servers on different sessions. So somehow you can act as the bridge between various communities allowing information to spread. But each community can still enforce its own rules around what information it stores.
The main difference to the current Fediverse is that federtation happens user-to-server, not server-to-server. Ultimately, each server has full control over what it stores and shares. Ana each user has full control over what server they want to listen to.
