Being an administrator/moderator is a big responsibly. Sure, if it's a small time forum, maybe nothing really bad would happen if someone gets banned,well you know, because you wanted that way. However, different platforms can have a detrimental impact on ones life, including employment, status in the society and so on. The worst part? You don't start measuring the throne of power immediately, you gradually descend into it. You start normalizing things you couldn't just a few months ago. I know from my own work that ultimate access and control of everything can poison most. You get these little challenges every now and then and you get tested, and eventually, depending on one's nature, you either say 'screw this,I'm not doing it' or you become a despot.
