My situation has turned into quite the pickle, and tbh I have no solution beyond just waiting for the guy who is doing this to get bored and stop.
Basically whats happening is this,

I somehow someway have angered a very VERY petty individual, who has decided to extract his petty revenge on me by constantly bc'ing ''free bfg [insert farmable here]'' and linking my world. This causes a group of 15-20 people to storm in and demand to know where the bfg is. This bfg of course does not exist, and they all scream at me for being a scammer and call me names.
I can't report anyone since I don't actually know who is doing it, and even if I did I doubt it would do me any good since he's probs not doing anything technically illegal.
