Racism and Reporting

So I just had a game where I hadn't typed a single word all game. I wasn't doing so well, as I don't play Ryze but would like to learn him. In essence, they didn't like my poor play, and my teammates started referring to me as a "%%%%%%" and a "%%%%%." After typing in allchat that I would be reporting our Caitlyn for racism, Vayne then called me a "%%%%%%" as well. I reported them as normal and I would have moved on from the subject except for two things. First Blitzcrank said, "are you even black" and proceeded to tell me that I couldn't be offended by his use of racial slurs against me or another. No, I am not black, nor am I Asian, nor am I personally offended. I do, however, have a problem with people using slurs in any case against anyone. Second, they then told me that because the system is automated now, that they would get away with no penalty even though this type of behavior used to get people permanently banned when we had the Tribunal. I understand why we no longer have the Tribunal, but I sincerely hope we have people reading over reports regarding racism and hate speech. Spending all of the hours and manpower on reading over reports of toxicity, I get that would be a bit of a stretch. However, if we aren't taking things like blatant racism seriously, why bother with a report system in general?
