In Rocket League they have built in a way to help stop chat spam. If someone spams the same quick chat multiple times in a short period they get a small chat ban (ie: 7 seconds). Then if they do it again (probably within a certain cooldown period) they get another longer chat ban. This continues getting longer and longer until eventually (I assume) a permanent ban.
This could help prevent things like "Roll on deck laughing" spam and pet text spam.
