That's basically how lobste.rs works. The invite graph is also public (see https://lobste.rs/u https://lobste.rs/u). It works fine, but I wouldn't derive too much data from it, since it is a small community, and spammers / vote rings are rare enough that a manual approach works. Another feature that I wish other places adopted is a public moderation log (https://lobste.rs/moderations https://lobste.rs/moderations) where users can see all the actions by the mod team. This helps keep the mods accountable.
