Modlog, which includes a site ban—something only admins can do.
The community bans also include communities that aren’t moderated by any instance admins, and some that are only moderated by a single person who likely isn’t aware of actions taken under their community’s name.
It’s my impression of solarpunk, as a general movement moreso than slrpnk specifically, is that the focus is more on local community mutualism than Soviet style central planning. I also think the only way forward is communism, I just think there are many intermediate steps necessary to get to stable communism on a national scale. Strong unions to worker co-ops to market socialism, and so on.
My main ideological gripe with the tankie instances is the impatient insistence on skipping all those steps that build informed consent through a gradual raising of class consciousness in the proletariat, and going straight to a national scale revolution.
