It seems more like being an ass just for the sake of being an ass. If you're going to mute just do it and move on. Announcing it looks just as much like a cry for attention as an all caps topic title from my perspective. No one is going to stop people from making topics like this. No one is going to stop people from making the just as annoying "muted" comments either. What you're saying is just as important as what the OP is saying, which isn't very.
