I'll admit, I will steal other peoples kills if they hop into my world and start killing monsters in the same spot. I also half kill if someone hops to my world and starts slowing me down. For example, I was at aviansies and there were two other people there, none of us tried stealing each others kills or anything and then some kid logs in and we attack the same aviansie and he then says "off" and I'm thinking, is he serious? He then proceeds to attack the two that were spawning by me so I stole his kills or half killed them and let him finish them off lol. He eventually hopped after insulting me. I wont hop to a world where people already are and steal their kills though.
