You people that are being upset by this are fucking retarded. You are the worst kind of people, those who search for things to be offended by to feed your victim complex. Go and die.
(Yes, this is a personal attack. Feel free to report me. I will feel free to not give a shit.)
No permanent change was made. Your precious avatar will be back when the joke ends. But nooo, you have to ruin everyone else's fun with your pitiful whining about inconsequential bullshit.
If anything, your avatar should be changed to a giant wrench, so everyone knows what a fucking tool you are. Or something like that.
TL:DR; Whiners FOAD.
