In my experience it depends on the sub, the size of the sub, and tightness of the focus on a single topic. Smaller hobbyist subs are often run by the truly passionate, giant default subs are usually run by ideologues and the power-hungry. In between is a mix of different motivations, ranging from "I want to be in charge of this propaganda" to "I think I can do a better job." A lot of reddit mods also seem to be disabled in some way, and basically have the time to be online 24/7 when not literally asleep. That creates a certain mindset and lack of connection to what the real world offline is actually like, and sometimes people get REALLY weird with that.
