They were (are?) a group that catalogued hate speech and general shitassery on Reddit. Arguably overzealously, but pretty close to current standards. Members were perceived as the Reddit boogeyman with deep connections to the admins and unlimited leeway. Turns out they were just a decade ahead of the times in calling out rape jokes and racism.
Samesies. I found it interesting that the people objecting to shit Reddit says post-2016 dwindled into… exactly the sort of people you’d expect. I don’t want to say that trump improved the internet, because he didn’t, but his election did let internet douchebags feel brazen enough to sit under the same umbrella.
