There's really only two types of people who get mad at mods:
The people who break the rules then get mad that they suffered the consequences
The people who see mods using the position just to have the smallest modicum of power over others and just reflexively swing the ban hammer without looking at context, seeing if there is a pattern, giving warnings, or anything else. They just remove and block what they, personally, do not like.
There's a boatload of both here, just as there was on Reddit. The differences are that it's smaller here, so you actually see the people complaining about the mods and the modlog is public so you can always see if the mod's actions were reasonable.
