I was in Inspire space park, minding my own buisness, and out of nowhere this poofer with particles named "goonsquad" and started using my username as a way for it to grief, I did not, and I would never say this, but this item used my username and started posting "goonsquad is Raping yo sims F***** yo b******." I then teleported home, should I be worried about it?
