How to apply censorship to custom chat?

Hello I've been working on a custom chat system for my game, however I've ran into an issue, how do I detect when one curses, without having to write every single curse word in the book. Currently you can foul mouth all you want, this is an issue though as I would like this game to not get stared down by roblox admins, is there a way to use roblox's censorship system in my custom chat?
