Report System Gives No Satisfaction
Think about the last time you reported someone for a clearly reputable offense. Did you get the notification that your report was addressed and the person was punished?
It seems like even though their offense is recorded in the chat log, they can get away with it. Even if it's a one time flame they should still get a penalty so they don't do it ever. Every reportable offense that is documented in the chat log should be punished because it's undeniable they did something toxic.
If people are punished every time they do something toxic then people will stop doing toxic things.
And the feedback for reports needs to happen. That way people know they're making a difference.
