The day I got xbox and xbox live (first day it came out, mind you) I got "avoided" because I destroyed people at a game, like said in OP, and So now as more and more people did that, 79% avoid me as "unsupporting". I have no "Trash Talk" or any of that other option either, only unsupporting because that's all butthurt people can do. Also, I have never preferred someone or avoided them ever.
