The instance admins of lemmy.ml and lemmygrad.ml, who are also the developers of Lemmy, have a wide variety of harmful views including genocide denial, transphobia, and support for authoritarian regimes. They are incredibly ban-happy and spend an unreasonable amount of time removing dissenting opinion from their communities instead of developing the platform. They've got a bunch of people in a complete echo chamber where saying anything critical about their favourite regimes earns you a ban despite there being no rules against it. Their users tend to also be the genocide denying, authoritarian bootlicking type.
