The macro "F You Macro" for "Discord" can be downloaded and used on any mouse and keyboard. Installing the macro is very easy in the Keyran program and increases your skill level in the game, if you follow the instructions!
When the macro is clicked, the message «F*** You!» is displayed and then sent. Quite simple, it is typed very quickly. I don't know if there is something like this already, but the title speaks for itself. Useful in disputes, presumably?
