I would say db0 has had a few red flags here and there, but they're still far from being the 4th Tankie instance

Keep in mind tankies have been known to create accounts on non-tankie instances to create this sort of division and generally troll

i def agree that /0 is having a lot of flippancy and groupthink issues, but i would not call them authoritarian. i would say it has true leftists, just a culture of extremely mean ones who don't need too much evidence to be persuaded into exclusion
