So, uh, this Cake_Tan guy seems to be indiscriminately homicidal. Now, maybe he's discriminately homicidal, only targetting the members of the community he had a part in bringing to the game, but I wouldn't know. All I know is that he's attacked and pursued (including trespassing) a few new players around me.
I wouldn't have bothered with this if there was anything else I could do. When he attacks, I have no counter. If it was at all plausible, if he had even wanted to, to follow me around the world, I'd stop playing right now. Running for a while is the only choice, after all.
