Seriously, wtf is going on with all of these mint-green background avatars? Seems like every single one of them is spam. Make them stop.
I continue to spot check them and they are all basically the same and they are all spam.
I've noticed the same. Just taking an arbitrary snapshot of recent followers, the green is obvious. Who would come up with the idea of using always the same color in the avatar? It's so obvious that something is fishy.
They all would like to try and impersonate @pugson. Figures.
