Yes, and highly ironically, they act as teen edgelords and some people get banned precisely for being Marxist Leninists. Notably, the bans are often instance-wide, not just a community, and include being banned from communities that the recipient has never so much as heard of, much less posted problematic content into. Even a single sentence such as "the Tiananmen Square massacre actually happened" seems enough to trigger that. In short, like "conservative" Trump supporters in the USA, their claimed political affiliations are beside the point, and the reality is an echo chamber of misinformation and circle-jerking.

The caveat is that the instance admins also include developers of the Lemmy sourcecode so... Also it is one of the oldest Lemmy instances, predating its spread out to the rest of the world. Hence other instance admins do not want to defederate from it. Upcoming updates to the Lemmy sourcecode are also exclusively posted there (afaict, I mean other than raw GitHub).

Anyway, the people who get incubated inside of that echo chamber then come out into the rest of Lemmy, and many of us do not appreciate that.

The more you know.

They tend to actually remove comments for being chauvinist and for some reason that seems to rub certain people the wrong way.
