To be honest I think it shouldn't be banned as it's nice to know who's an -Yoink- or any other annoying player. So when I get t-bagged I just do it back, as it does not do anything and is just a victory dance.
Matching with bad players is a problem for some, that is if they can't carry. But if your -Yoink- at carrying then play BTB, warzone or FFA. You don't need to carry then or just get some of your friends to search with you, very easy way around...
