ok, let's define admin abuse, destructive behavior to harm another or to abuse power given to them by a command to hurt and to be a "god" or ruler above the little people.
that being said on my server I abuse too in a sense in my com center that is for public use there are unclaimed aberration shoulder pets unclaimed and available for anyone to pick up and have a new pet. Or right now there are three vaults unlocked each one has leech blood, rods, and honey inside there for the all-day fishing event. or another example ill go in spectator and give people max lvl jerboas that they can tame so they can get higher lvls then the level ones in the wild. but im quite open about when i need to use the time of day cheat to see if the lights are to bright on the water at the fishing arena and i will ask if its ok first. so yes in a way i do "abuse" but i keep my server health in mind and my 900+ people seem to be ok with what i do so not every host is the same were not all power hungry the good ones are out there and we still use commands and our people are ok with it
