Mods of !news are now banning people for criticizing the MBFC bot?

I got banned earlier today with the message "rule 1", no other information about why, or which comment broke the rule. As far as I can tell it was this one, which just says "We want the bot gone. That’s it. It’s really that simple."

So I checked the modlog for other bans, and @[email protected] was banned today as well, also just for "rule 1", probably either for the comment saying "a stupid bot writing useless bullshit" or "This is what you call "Not listening to criticism."", neither of which are an attack on any person.

(Also earlier today @[email protected] was banned with the message "fuck off", which I'm pretty sure is not a reason to ban someone from a major community, but doesn't appear to be related to the MBFC bot.)

One more today, @[email protected] was banned, again just "rule 1", last comment being this one, again not an attack on any person.

So what's the deal here? I couldn't find any rules for mods on lemmy.world with a brief poke around, but are we letting mods run major communities like little fiefdoms, banning people for criticism?
