Bad moderation can also drive away good people and good discussion.

I still tend to keep up with most Android news on /r/android but the mods there went super full crackdown on moderation the past several years, constantly removing threads for minor infractions of the rules, and breaking up good discussion in the comments section of a post because the OP was breaking some rule or another.

I'll tell you the reason that sometimes stuff gets removed for "minor infractions" is because if you don't people keep doing it and referring to those things that are minor infractions. "why can they do it but not I?". It just causes drama and I think the majority of the moderators are doing it for free on their own time.
