I am going through the same problem but instead I am being harassed because I joined a halo online game and I wanted to play with someone in the server that I thought I saw before which there was someone I saw before but I wasn’t talking to them or reacting
with them and then they started saying that I start problems because I killed them onlineOut of self-defense because they were going to kill me which you shouldn’t be getting super mad to the point were going to send someone hate messages but then their name
is [mod removed] and and I asked him to please stop killing me I meant to message the owner but I accidentally messaged him and then he message back their orders but before that I meant to send that I killed you in self-defense and then I saidWell can you
tell him that I am friendly and they said get out then and I said all I want to do is help and I said OK because I know I walked out of the building that I Spondin then they told me to leave the game I said no I just wanted to play random games but you guys
