Rspamd is a great example with content scanning and local reputation scores. RBLs work on finite identifiers that have *some* cost. Nostr works on infinite numbers of pubkeys. This is the approach I am working on with nostr.land, where it combines multiple different types of information. Such as blacklists, historical reputation, but also content analysis, network, etc. The goal is to make it work for 99% of new users. The other 1% can solve a CAPTCHA and wait a bit.
