When power gets out of control

I think we all can agree a lot of people in charge such as admins, mods or even world leaders use their power as a scare tactic and abuse it quite often. When do you cross the line of keeping people in line and just abusing your power?

when you aren't actually doing your job, you're crossing the line. that's why clear rules for mods are neccesary. i don't know if mods here have those, but if they don't.... poor decision. :P BUT FOR CERTAIN REASONS... it is neccesary on this site for admins/mods to abuse their power at times.

As always, context is important, and the kind of use of power should be considered necessary. The only time I would consider always an abuse is when a mod is doing something like teasing someone incessantly(through bans, kicks, or deleted posts that are taken back immediately or something) or getting something very private out of someone.
