It would also negatively impact those players that want to send a <S> after the fight or talk about the how, what, and why's of how they lost. I've had many a fun conversation immediately after a fight win or lose would hate to have to wait a minute do to that
This, some of the best ppl ive met in the game were red gents that I shot down, or vice versa. Ill PM ppl, but its to say, great shot, or nice shootin or to let them know what a blast i just had fighting them. If i get "ho'd" or rammed or bombed, its all just part of the game, and I know that every time I play. No need to mute someone for any length of time just because they like to send ignorant PMs.
Take the high road,Ignore them, squelch them, or just laugh at the fact that some idiot is sitting at his desk getting upset at something as trivial as a game.
Just my $0.02
