No, it's just that they don't really look good. At least in Grace, Mike, and Cami, and mine's opinion. (Okay, that came out weird. xD) But it's also if someone wanted to make it so that it's ( :: (NAME) :: ), they'd have to do it like how I just typed it unless they want it to have two smiley faces at each end. It would be nice to have it automatically disabled, mainly because it's not really like anyone but us would notice and that they don't really look good in my opinion.
