Like detecting web adress sent, emojis... and replacing them with something of our choice

An example of this?

emojis sent from discord appears like this ingame :smile: so it would be great to automatically replace it with a :-)
but not limiting it to emojis but being able to add anything we want to replace in a file like replacing a discord invite link to censure it or name of another minecraft server...

This would require far too much manual work. There are far, far too many emojis. The character being conveyed with the name alone is good enough in my opinion.

I don't ask for something you prepare yourself, just the possibility for server owner to add blocked words and rewrite them by adding them to a config file (I would add emojis in my server but maybe someone else would add censure for keywords like discord invite, website link...)

@DevilScarlet We use VentureChat and it can filter both Discord > MC chat & MC > Discord chat (we use it for swears, but could be used to the emoji's as well).

DiscordSRV will probably never edit Minecraft chat messages, that's off to other plugins, DiscordSRV just relays messages to Discord.

Could try something like EmojiChat (supports DiscordSRV) though requires a resource pack, https://www.spigotmc.org/resources/emojichat.50955/ (for displaying emojis in-game)

#507 also seems relevant, in this case
