Do I ever get my two week ban off my "record?"

I didn't say the rules were good, I just said that they were the rules that we play by when we play the game, like it or not

Trolling and intentionally feeding are far more complex and League specific problems compared to toxicity. You can't easily modify technology for catching trolls in another game and modify it to work with League of Legends, since the troll behavior is different. You also need to verify that feeding is intentional, not just a bad game. On the flip side, you can modify technology based around text recognition to identify toxic language patterns fairly easily.

Add to that the perception factor. When people think of League of Legends, they don't think "Oh, they're such a troll community" or "Oh, they're a bunch of intentional feeders", they think "Oh, they're a toxic community". The priority for Riot as a company would be to fix the bad PR that negative impression about their game. This brings focus on cleaning up toxic language in game and trying to prevent it from happening, rather than trying to ignore it. It's important to remember that ignoring it (a la muting) doesn't mean it's not there, and ignoring the toxicity of the community wouldn't make the community any less toxic, and the reputation for being a toxic community would remain.

As for manually verifying the games, they tried that first. That was the Tribunal system, and by all accounts it was too slow to act. People got bans for things they said or did months prior that they didn't even remember doing, just because the system was flooded with so many reports. There were also (although most likely a minority) people who would brag on the forums about how they would always vote to punish people, or how they'd end up judging their own actions on another account. I think the biggest push for Riot to make the automatic system was to get the delayed feedback down significantly (down from months to minutes is pretty significant) and to remove false "punish" judgments.

Riot's mentioned they're working on changes to the Tribunal system, and intend to have both the automatic and Tribunal working at the same time. I suspect that the automatic will be used for the cut-and-dry cases, while games that the automatic system is unsure on (and most likely not punishing right now) go to the Tribunal. To combat the false positives, Riot's mentioned that they'll pass the Tribunal some good behavior and neutral behavior games, and if the players passing judgment don't look like they're actually looking at the game reports they'll be removed from the Tribunal.

Riot has said multiple times that people do not get punished simply because a premade reported them for no good reason. Four false reports are still false and get thrown out.

Yeah, but what if you said "buttface" or something during that game. The automated system, targets that word as a threat and makes those reports count.

So if you start a game joking around saying "Gromp has a silly buttface" and the other four start smirking and report you later, the automated system will punish you. It's bullshit.
