Getting banned for flaming trolls

I just got permabanned because I flamed in chat a guy on our team that went 0/15 on Heimerdinger after not even 20 minutes. He was costantly trolling, using zhonya and summoners for no reason, suiciding against the enemy team but in a smart way. It is true, I have been playing for a while in silver/gold and Riot Support just looks at chat logs. They don't give a flying fuck of what happens inside the game. Literally, one game out of three, there is someone who deliberately acts this way, just for the fun to get people raging at them. And you know the saddest part? The one that will get punished is gonna always be the ones that rage at them in chat. This is the main reason why this game is so toxic and this is the main reason why the game is gonna slowly die. You can be allowed to do literally ANYTHING in the game, as long as you don't flame in chat. I have been playing LoL for more than 6 years. My only suspensions have been a couple of chat restrictions and a 2 week ban always for flaming trolls / hard inters in game.

Of course, the fact that I never spent money in the game had a big weight as well, I suppose (before someone starts complaining about this, I have been working in Customer Support for f2p games for quite a while, I know that this is exactly what happens when support receives a ticket. First thing to check is how much money they spent ingame).

I am not even mad at the permaban. I will invest my time in somethign more productive than flaming at frustrated people. It is just sad to see how horrible is the support of a company that has always been highlighting how much they care about their player base.

Protip: if LoL is recognized as the most toxic game ever, start asking yourself why, before it is going to be too late.
