Punishment-Free System
I came to the conclusion by my own research that its pretty hard to get punished in this game. I've reported my fair share of players and even took screen shots of offenses from about 15 different players. When I say my own research, what I did was track these players through OP.GG and saw from the date that I reported until now, they have continuesly played games (match history). There was no large gaps (at least 14 days)between games. This meant that they did not receive at least a 14 day ban. These SS were taken mostly during August. Of course there is no way to track chat suspensions but the offenses these 15 players were at least for intentionally feeding / racism / hate speech on the level of: 'get cancer'. 'kys', 'i will murder you and your family'. So it definitely possible that some of the 15 players got chat restrictions as punishment. But having to research 15 players, I found none got a 14 day suspension. So my conclusion is you must be a serial toxic/troll in order to receive a punishment as severe as 14 day or permaban. I guess infrequent raging/inting/trolling is okay.
I'm done with the IFS. Its wasting my time. I understand that this game is filled with toxic players and its okay. I'm just going to play along and do the best I can. You want to call me trash and tell me to uninstall. its okay! you want to tell me to kill myself and you'll kill my family. thats okay too. you want to steal my buffs and ban my picked champion (not even meta champ) thats perfectly fine.
I won't waste my time reporting. I don't blame Riot at all. I'm thankful they make a great game. I guess over the past 4 seasons, I've developed a numbness to all the toxicity. I don't even have to mute anyone because chat rage doesn't really bother me.
