Shitty mods was one of the worst things about Reddit. I've been banned, silenced, told me what my opinions are, and totally steamrolled by mods.
One time, I started a Discord server with the same topic as a sub, and invited people to join. Within hours, the mod of the discord deleted my thread and banned me. They said that "this is not how you create a Discord server," started their own, and created their own post. Guess which server for more popular?
I confronted them about it, and they said they they banned me to (exactly their words) "get my attention," even though I did not break the rules. A power trippy mod just power tripped again to power trip over their artificiality-popular Discord. What a piece of shit.
There are very few larger communities that I know of online where there isn't stupid under-handed shit. People sink further into their chair and think that they know better than you simply because your opinions don't line up with theirs in some way.
