This would probably affect normal things like prices of stuff (in some currencies especially) and a lot of accidental filtering of. Eg how many users does nostr have... 24k or etc etc lol. But maybe this would be too much to ask for. I'd live with the mistaken mutes  

 You could add stuff like reaches or fiat price to narrow it down a bit. But you would have a lot of scenarios to consider

 /d/d[kK] and /d/d/d[kK] would mute two digits followed by K (lower or upper case) and three digits followed by K nostr.data.haus 

 Regex mute lists anyone? 🤔
