There is a lot of easy restrictions to add that would make literally nothing worse for usability while already constraining a lot of toxic behaviors.

- Hello! being only usable during the preparation of games
- Good match! only once a game has ended
- Negative markers only usable on opponents (who uses them on team members besides griefers?)
- A game option to turn off quickchat sounds, and the best would even be able to turn on/off the ones we don't want, and keep the ones we want.
