Isn't a blacklist typically a bad idea for all of the reasons people are listing in the comments (like scunthorpe)? I've never implemented a social media platform, but why would you use a blacklist as opposed to a flagging system with manual moderation (where maybe the flagged user gets sent to a quarantine where they're shadow banned until approval)? That way, as language evolves and new slurs are made, or somebody tries to circumvent the system, you can just manually ban that user. Is there a technical reason this is a bad idea?
