"Ha Ha, U Mad."

This... really needs to become a bannable offense of Verbal Abuse. Nothing is more annoying than watching someone say something rather innocuous in game, or attempt to banter, so half the game starts spamming them with:

"Haha u mad. Calm down bro just a game." "Relax dude." "Don't get all angry bro."

The good part is that they proceed to do this to said player for the entire rest of the game, even if the player apparently muted them since the original player long since stopped talking.

The great part? The system sees this as perfectly fine behavior.

Spamming is spamming. Harassing someone is harassing someone.
