Someone that I have blocked and along with many of this person's alt's keep sending me 1L almost everyday. Is there a way to stop this person. I don't want to interact with this person but this person won't leave me alone. Is there anything I can do besides blocking and reporting him. I might also add this person told me to kill myself.

There was a region restart and i got kick then all of a sudden i am getting that error can not connect to simulator. I have looked at all the answers on here but still no way of getting booted from that group.Please can someone help me?
