generally games that provide such powers to players has a sort of tiered power approach when you first are given said authority you have limited in game powers and as you prove your worth(by not abusing powers and so forth) then you are granted additional powers. so you prolly wouldn’t be able to ban ppl to start you’d prolly be able to kick and report to a gm who would then deal with it further, that way if you kicked someone incorrectly they just have to log back in the worst they think is they got d/c.
