Let's start with why it was removed;

The tl;dr is Tribunal isn’t coming back any time soon.
We learned a lot from Tribunal when it was around, and it actually became one of the bases of our current models for abusive chats. A player-voted service like Tribunal comes with two huge drawbacks that are really tough to get around, though:
- It’s slow and inefficient. Manual reviews require pulling those chat logs out to the website, waiting for responses from enough players, and deciding on a penalty from there, while the current automated systems can send out penalties in less than 15 minutes.
- It’s sometimes wildly inaccurate (especially when there was an IP reward per “successful” penalty, leading to a super innate bias in the system).
There’s a couple of things Tribunal brought that we know we haven’t tackled in a big way, like more focus on trolling and intentional feeding detection (though we are continuing to iterate on how we detect these) and more agency to make it feel like you’re really having an impact on unsportsmanlike behaviors.
We’re making a lot of progress with dodgy chat content and the new name filtering service with our automated models, but we do still need you to hit the report button when you see bad shit to help us gather information on what you don’t want to see in League. It really does make a difference.
You are correct it was inefficient. A Rioter had to manually pull the logs, manually post it on the website. After the voting was done, the Rioter had to manually check whether the vote was correct.
The thing the tribunal was good for was to provide some visibility to the community and make them feel they were contributing.
