yes there are too many, but people here whine about everything, say that the mods are too heavy-handed and oversensitive. They don't want to be infracted/banned for swearing, taking petty shots at people etcetera, but now you want to curtail freedom of expression. Everyone has a different threshold and I don't want you deciding the 'taste level' around here.
Besides, Hian contributes nothing of value so you can just put him/her on your ignore list and not see the gifs (and not worry that you are missing any good posts).
I thought it was just him, but it turns out there are sadly more.
