@Riot could you add this to the game?

Can you add this to the chat box? You'll see this before writing something.

It's something for the flamers maybe if they see something similiar to the text ''Say something nice :)'' they might change their mind and won't flame at others. Or have something written like ''Think about the consequences of flaming!''. Adding this shouldn't be a problem and it won't have any negative impact on the game itself. Even if it changes the minds of a few flamers, that should already be worth it to add it to the game!
