sure, but why didn't the admins just advertise their real politics instead of pretending they aren't prozionist

Not everyone. I dont make choices based on politics, because I do not engage with or participate in politics as best I can. Especially here on Lemmy.

As a mod for .world/c/cars, I only make choices based on the rules of the community and instance. I might not agree with a post or comment, but if it isn't breaking the rules then I don't do anything about it, and if its reported content then I will just close the report. Admittedly, its pretty low traffic so I haven't needed to do much, and the other mod is great and handles things usually before I need to get involved.

I believe it is the responsibility of a mod, admin, or other figure in a position of power to not abuse that power. Fair and equal application of rules, extending the benefit of the doubt but still firm about the rules, etc. are ways to avoid this IMO, so that is what I try to do.

Someone having a different opinion or belief should never be a reason for mod action, even if I think that opinion or belief is wrong. Unless it is against the rules (or clearly dangerous such as suggesting drinking bleach for any reason), it should be allowed to be said. Users shouldnt be afraid to have posts removed at random or because I dont agree with them. Sometimes this means a new rule needs to be made, and thats okay.
