The 360 also had this feature and basically no one used it. It was called a "prefered player" option or something, and you could list a reason why you no longer wanted to play with that user such as "trash talking", "leaving the game early" and a few others. This built a reputation for you which you could view, and then "improve upon" because it told you who anonymously disliked you and their reasons for it. Alternatively it also told you what they liked about you if you were rated as someone they'd like to play with again.
Again this was very rarely used, at least from what I've seen in the 4-5 years I've owned an Xbox 360. Not only with my experience but with my friends and family who also owned Xbox 360's.
