Who cares? Badges are like belts in martial arts, its a personal proof of a certain accomplishment. It wont give you any advantages in game and you know if you got it by cheating the system or actually earning it. Also, if your premade gaming friends see that you have it, and also know that you are a mediocre player, they will just think you are a fraud and you lose respect.
I got both the 20kills badge and 4k dmg badge on my smurf. I got both of them the same game which was the second or third game on that account. I dont know how it is now but back then, you got matched together with total noobs the first few matches, and back then, I was at a "2500k dmg-badge level". So needless to say, I went through them like a hot knife through butter while they tried to figure out how to switch from melee to their weapon =) But those badges means * to me, and I dont wear those badges when I play with that account, because its just embarrassing.
So if some loser wants to wear a 20kills badge they got from Shadowfall, let them and just kick their sorry butts in game.
