2.6 Valid KOS Reasons
There are many KOS reasons and they all work in different situations and scenarios, here are a few:
- T-Baiting as an Innocent, for example:
Pushing someone with a crowbar near an edge or hazard.
From what Insanity told me, you tried to push him into an active T trap so he killed you. You have not provided any evidence of this situation and a staffs word is finale.
EDIT: Also, your attitude in-game is not the best.
