I admit I shouldn't have accepted the tp, as this person took me to the nether and took my stuff, but that doesn't bother me too much. What he said after put the nail in the coffin for me. I just don't trust his attitude. Link to the chat log: https://imgur.com/a/F9ZACPe
Totally valid report because the teleport request was maliciously intended as a grief-scam which is clearly against the rules. There is no excuse for an "elite" ranked player to blatantly ignore a main rule. I also agree that the language used and way in which it was delivered would at least be punished by mute. However the griefing would over rule it probably by a ban of some length. The only thing you didn't include in the report was /realname or the actual username for identity purposes. Either way, staff will know what to do.
Teleporting people into the Nether and proceeding to kill them and steal their items is against the rules and Sheshton has been punished accordingly. I can return your inventory to you. Next time you're online, type "@Kakalavala" in chat and I'll be on shortly to return your inventory to you. Thanks for reporting this, we do not condone this type of behaviour.
like DC mentioned this report is in my opinion totally justified, the chat alone would be worth a mute and a warn. You shouldnt be afraid in theory to teleport or use warps as they shouldnt be traps in the first place.
