Overpunished?

So for context, because seriously, context needs to be taken into account for these things. I was honor level 5 since... august? Maybe July? And I've kept this up reliably, received honors constantly, and I've been playing a lot. Then not quite two weeks ago somebody reported me. Several days later, and I got a chat ban for ten games. I played a game or two, then stopped for a few days because I got busy. It wasn't until a few days ago that I was actually given a reason why, the chat ban was refreshed to another 10 games for some bizarre reason, and my honor level got locked down at 1. Let me be clear about this: I was rude. I was not well behaved in that game. Do I think I should have been unpunished? No, of course not. My good history doesn't excuse me for bad behavior. My point here is the way I was punished was way, way, way over the top. Knock me down an honor level or two, sure. I had that happen last season, and when it did I did my best to mute toxic players. I was shown what I did was not okay, and I responded positively. I recovered my honor level in less than a month (2017, mind you.) with beaming behavior, good gameplay, and just generally spending my time teaching other people. I take pride in being helpful, which I wish was still an option for honoring.

So this person reported me because, throughout the game, I called them out for, in short, intentional feeding/running it down bot, building nonsensical items, and telling the team to kill themselves because they were "useless". Most of my responses were in the defense of his Jhin support (Sure it was a trolly pick, but he was trying and doing well. He made it work.) that he was telling to go kill himself, endlessly. I was even on his side at first when he was mildly angry, because seeing support pick Jhin is damn annoying. But Jhin more than carried his weight, and kept trying even as this ADC ran it down bot, built no completed items, just components until near the end of the game, and we were losing. Between me and the Jhin, we had a fighting chance. So I shifted from irritated at jhin, to irritated at both, to siding with jhin because he was doing his job as a support, and the adc was just... sitting in bot lane, letting himself get killed by farming in front of opponents (As in he farmed, they went all in on him, and he didn't fight back, just kept farming).

Meanwhile, he's verbally attacking our entire team, obviously more directed at the Jhin. I retaliated. Obviously I shouldn't have, especially in the manner I did. But I really wasn't terrible. I didn't tell him to kill himself. I didn't use any form of discrimination. I wasn't even offensive. And he just runs his mouth about how we're retarded and should kill ourselves, even our teammates that were silent, uninvolved, and were simply losing lane because, sometimes, people just lose. It _happens. Nobody wins their lane 100% of the time.

So after this game, he reported me because I called him out (Rudely, sure, but it sure as hell didn't come out of nowhere), and I got chat blocked for 10 games, and honor locked straight from 5 to one. Since I was actually alerted to this, I've been grinding out games like a madman for most of this week, been getting honors left and right. I even started using /mute all to make sure I wouldn't see anyone running their mouths and feel the need to talk, and nobody would report me for chat. And yet I'm still locked. Outstanding behavior, even to the point of getting an unusual amount of friend requests from other generally nice players, and I'm still in the same spot.

I understand that poor behavior needs consequences. A chat ban for a week or two would have made sense. But removing my year's worth of good behavior for a single report, that wasn't even that extreme? Especially when, in-context, I was responding to a person constantly telling me and my teammates to kill ourselves? Seriously? Even when you take my chat logs for that game out of context, how in the world did it earn me the same punishment as a person that is consistently racist, offensive, insensitive, and any number of things that really ruin a person's day and make them feel terrible about themselves? I told a person that they weren't contributing to the team whereas everyone else was, things they were saying weren't making sense (because, in all seriousness, his grammar near the end of the game was so broken I couldn't actually understand what he was saying anymore, and he was speaking just fine for most of the game), that they were actually just running it down bot lane, and they had no right to tell everyone to kill themselves. I'm pretty sure the Jhin even honored me that game despite me being against him at the start. But no. One report for being generally rude, and I'm treated exactly the same way as a person that harasses people, discriminates, and goes out of their way to actually make people want to kill themselves.

So here I ask: Why in the world was I given the most extreme punishment possible, when there are obviously more equivalent alternatives (i.e. honor demotion, temporary ban from ranked)?

Edit: I've been logging on repeatedly for the past day to watch for new loot stuff and any news, without playing any games, and I_just_ got my honor unlocked, in the wee hours of 11/4. Seems like there's even more background stuff going on, which I'm pretty sure I've guessed at correctly, to hide how it actually works (meaning I've guessed the mechanism of hiding, not determining actions relating to the honor itself). I appreciate this sort of thing, but my question as to why I was punished so severely remains unanswered.
