Fistrushing?

well today i was at theend with some friends of mine fighting the dragon. it was not long that i found out that this was indeed a pvp area. i was attcked many times by someone covered in diamond armor i went back and forth from my house to theend, to get more armor and more potions. i gave up after a while and had waisted at least 2 stacks of iron. i just started to fist rush for about 60 seconds i might have been warned but i didnt see the message. i run a hotel in peaceful with 2 guests in atm i would love to keep running my hotel and i am truely sorry for what i did and it will never ever happen again.
