Hey all, author here! This is a demo of the rules engine we built to fight spam/abuse on the internet.

How The Profanity API solves this: I built a 5-layer detection pipeline that analyzes content progressively: Blocklist (L0): Your custom blocklist for instant flagging Static (L1): Exact match against known profanity…
