From what I recall, griefing has not been allowed. Allow me to present some proof to show that my actions were justified.
Griefing - Official TF2 Wiki | Official Team Fortress Wiki
I quote:
Attacking your own teammates for long stretches of time for no reason besides to annoy them, especially with the Frying Pan.
Though we were not teammates, you went friendly and simply went up to me and kept spam hitting me with the pan to be annoying.
I did warn you to stop several times, slayed you, and kicked you. I did do this but this was properly within the orders of dealing with rule breakers. GG kid, but I did my job the right way. @Hachi unmute next time :coffee:
