if you ever have a chat filtering system, the best way to reduce people attempting to bypass it / cursing is actually to censor the message for everyone except the sender
If you censor it for the sender, they will likely go and try send whatever they wanted to say again and again until they find some variation that bypasses the filter
It becomes very hard to bypass filters if they don't even know their message has been filtered in the first place ðŸ§
