Zero tolerance for free speech but ofc they'll take your money.
I understand guiding sportsmanship and trying to create tolerance and a positive atmosphere, but there's a reason the US had speak-easies in the Prohibition, and there were sympathizers during the Holocaust, and a resistance during every source of free speech governance. When it goes too far, it creates a much more toxic and dangerous environment out of protest than having a moderate policy that everyone understands.
Sometimes the current riot rules are not "human" rules. They're tighter than rules that any other game that aspire to be sports in the name of sportsmanship. They're tighter ToS than any program that aspires to be a game for fun has. They've brought it to a point where they have 0 tolerance for anyone, and bet on keeping their player base through addiction, rather than Sportsmanship. Those players who actually play this game enough to invest in it, can spend $1000+, get banned, and Riot knows most of them will just build another account. They will respend on the next account, and Riot will "pretend" that the argument that money matters in preserving an account is a negligible one in the face of "a standard of perfection."
I'm not bringing that up to argue that money does indeed matter, but rather, that the "standard of perfection" coupled with money is creating a dangerous precedence: A player base of addicts who know fully well they can get banned for being human, so they spend less, they care less, and make more accounts, act more toxic as a result of the policy. Sometimes, they just get creative and feed/bait fights in ways that won't pull up as positives to the automatic feedback system but ruin the game for everyone else, because Riot ruined the experience for them after they got punished for a human experience. And it's not hard. All they have to do is auto farm down a lane while they are feeding. Auto farm a jungle. Avoid just pure running down a lane and feeding and you're good. Ask questions which elicit toxic responses, and you're good. Just ignore all objectives and make sure you're at the other side of the map whenever they are happening. It's not hard at all to troll this game without getting caught. In fact, it's easy to get other people banned.
TL:DR: Over-regulation results in unregulated but nonetheless intentional behavior which hurts other player's experience more than the initial regulation did. Riot's rules are stricter than ever, but as a result, their player base is at its most toxic due to the system.
