Should Riot ban people for inciting toxicity?
Recently I was playing a normal game with some friends and immediately the other person was saying things such as "Why do you guys have to be a group?" and "You guys are all probably like bronze 1 without friends" in the champ select lobby. This was before anything had been said or done. So my friend responds, calling him a dickhead. Mostly because well...he was being a dickhead. So the game goes on and the player is constantly trying to get us to say shit throughout the game. The same friend gave in and called him a "%%%%" and other things of course.
However, despite the random getting reported for his actions, he received nothing. Then in the post game lobby he was calling us all trash, despite only having a mediocre 8/8/1 score. Yknow, normal random shit, however my friend who said two things the entire game gets banned for 14 days whereas the one inciting the toxicity gets absolutely nothing. Also, before it's asked, that game was the only game cited for his ban. So, why does it make sense that responding how one is prompted to respond is a bannable offense, yet prompting people to be toxic towards you is not?
I dunno maybe i'm talking out of my ass here, but what do others think?
