I see only OP calling for defedding instances that don't defed Meta. Fedipact https://fedipact.online/ makes no mention, never seen it on Mastodon. I think the flamewar should be toned down a little.
I've had multiple conversations about liberalism and come to realize there's a multitude of definitions none of which make complete sense. A left-wing definition might be "liberal democratic capitalism" like most of Europe is, with neoliberal being a more right-wing version of that like the US. A right-winger might use liberal to mean someone culturally progressive. Sometimes liberal is used to mean someone who wants a smaller government, sometimes it is confused with libertarianism (which was originally left-wing but co-opted by free market capitalists).
I don't think the term "liberal" is useful anymore, it's mostly thrown around towards people you perceive to be the status quo.
This instance is blahaj.zone, hosted by the folks at blahaj.zone?
This, except Librewolf on desktop and Mull on android to get some extra hardening.
I use Mull which is hardened for privacy. All Fennec derivatives support custom addons and setting the collection yourself is possible.
I'd wager a fake vote count would be much easier to detect than the same amount of fake users
