Support. This gets really old, really fast. Especially when they carry the advertising over to the direct chat @ home. Yelling is overused anyways, I don't want to sift through more clutter when I could come to the forums and look for somebodies video if I wanted to watch one. I get tired of sifting through typical shenanigans as it is, for example: pvmers getting upset that a pker killed them and the flaming that occasionally comes with it. I don't even bother when people start spamming, I just turn off my chats or go play a different game.
Also wouldn't be so bad if I could actually ignore people as well as have it carry over to yell.
