In the new voice menu you can look at a player and press Q, M, L to have the game check if they are a leecher and kick them if they are. The way the game checks is by forcing them to press M within 10 seconds.
This can be used by griefers to kick players from both teams even when they are not afk. Imagine someone who bound the Q-M-L sequence to their 4th or 5th mouse key through some automation program(AutoHotKey or similar) and runs around trying to kick everyone from the server.
This needs to be removed or modified ASAP.
