everyone seem to like to join the abuse

so was playing Veigar, i died once, had a pantheon verbally abuse me telling how he wanted to fuck my sister (i don't even have or even mentioned a sister). after multitude of level 1 deaths throughout the team fight (yes i'm at that elo) all the blame was put on me, within 3 min i had constant spam of swearing and abuse i decided to afk. won't lie i'll take the repercussions of that. however is it fair i'm allowed to be abused and i can understand i am suppose to mute, but if half the team is it really fair on players to sit their and mute everyone to play for people that just sit their and abuse them. i'd rather be banned from the game than play with a whole team that sits their and consists of abusing someone.
