There's a chart of things that give people a feeling of power:

Banning someone as a Discord or Reddit mod has to be right up there because nothing else explains their tyrannical fiefdom-like behavior, lmao

(TLDR: A subreddit mod trying to ban a reddit admin):

To provide some relief, the best "no-u" I've ever been personally witness to, was one moderator who went on a power trip and mistakenly tried to mute/ban me from discus for some contrived reason, and when he enacted the policy, the group chat policy bot banned him instead -- he soon afterwards realized that I was the owner of the partnered organization that was hosting the entire service

If only that could happen to Musky Husky, getting slapped in the face by the revolving door while holding his hall monitor pass

I certainly would not ban anyone critiquing me. I take it as feedback rather than a personal attack like the ones you're referring to.

I'd say most mods don't even pay attention to people critiquing them
