Tankies are people who play apologetics for authoritarian dictators who have claimed to be socialist or communist, and who will often excuse any action in opposition to “the west”.

More formally, they’re the cathartic branch of Marxist-Leninists (MLs). Lemmy’s a small space, and it’s a place that many MLs landed after bouncing off of Reddit, and the core developers count themselves as MLs.

The flagship Lemmy server is lemmy.ml, but the Tankie trolls have their own server, lemmygrad.ml where they go and be all 4chan-like.
