Toxic players

So i had a "one for all" game which is supposed to be for fun right ? Don't think so, atleast for that person a guy never stopped telling me to get cancer or to die of course i didn't pay a head im done with players like him but i do sometimes get in fights or go over the edge (i didnt report him because i believe everyone deserves a chance even if they come from hell) i would like to hear your experience with this and tell me how u dealt with it. Just asking to see if many people have seen something like this have a good day!
