It would have been far more efficient to implement a simple block function, which allows you to block players from being matched with you.
[1] Less coding and less bugs after update (an emerging tradition lately).
[2] Abuse-free, it only affects yourself and not other players. Even if you block everyone, then it's you who will have trouble being matched with someone.
[3] Discrete. Noone would know that you blocked them, thus no repercussion from other players for blocking them.
[4] A similar function already exists, although for communication only. Also editable on the EA profile page. Can be extended for MM.
[5] Less headache for the game moderators concerning reports, or posts on AHQ. You dont like someone, just block and problem solved.
[6] No logical reason to dispute, because it only affects your own gameplay, unlike your idea that someone's gameplay would be in the hands of others.
[7] Cheaters and hackers are like virusses, they adapt. All they need to do is to switch accounts.
