Think about when the average person ever has cause to interact with large community mods. There's your answer.

Had a couple bad experiences with the r/Linux mods, but other than that most of them are fine. I think users don’t really grasp what mods do, and the amount of internet sewage they have to sift through. And when they’re doing a good job, the users don’t notice it in the first place.

Maybe only users with bad behaviour have problems with mods and complain about it all the time. Similar to the police in real life.
