The Automated Reports/Bans are not Promoting Positive Play
I've simply noticed less people communicating in general, I would assume it is because of the report system. Then again, I've received Offensive Language in several games that I NEVER typed in. Sure, someone can this a "false report," but if that's the case, why was a notified before a human player reviewed it? Oh, that's right. Because the Tribunal is down and human review is no longer an option.
To be permanently banned for offensive language where there was not a curse word or offensive slur used is simply stating that players are not allowed to have an option or disagree with a "teammate." This goes against human nature. People complain. People argue. People fight. But then they eventually get over it and move on.
Which brings me another point I can't wrap my head around: Why does Riot's matchmaking system still match you with players you have reported and other blocked? Doesn't that defeat the point of reporting a poor player if they are just going to force you to play with him the next game and you have to pretend to be friendly with him knowing he doesn't communicate with the team?
