Please relax about ranked restrictions
I see so many people who frequent soloqueue getting upset about the ranked restrictions causing more toxicity in normals. Hopefully this will ease your mind. Probably won't but it's worth a try.
I have been banned/permabanned quite a few times. It's shameful but it happens. The first time was on an account I had since pre season 1 and it was banned at the start of season 3. I was never toxic, until I started playing ranked. When I am toxic, it is in response to other toxic behavior. NO It doesn't make it more appropriate, it's wrong to be toxic no matter what. This restriction helps me as well, because the type of people I react to, will likely be restricted as well.
Anyway, when I am in ranked, I am playing to win. On a permabanned account (ugh) I was plat 3 before seasons end. I played really well and rocked season 3! When season 4 started, I was really irritated with the new changes, and would take out frustrations in ranked games when people would do something to cause a loss, or talk smack to me. I overreacted. When that account was permabanned, I created this one. I was meh, for most of the season. Banned once or twice. Didn't care because screw it, all my champions, icons and over 700 dollars worth of skins are gone, so why care? Well that changed late season.
Now they have created this ranked restriction. I of course, got one. I am on it now. I have noticed (as a few rioters have mentioned) my attitude DRAMATICALLY changes from ranked to normal, and from normal to ARAM. In normals theres nothing to really lose (elo) so i'm not stressed about it when someone starts doing things to intentionally ruin the game, or refuses to take advice and continuatiously throws. (this is not me saying I don't make mistakes, but I take a lot of care to adjust myself). This ranked restriction forces me to play the more relaxing queue. I play better and am a lot calmer in normals. I am never toxic in normals. THis is a fact. I do not rage, I do not get aggrivated, nothing. I think there are different kinds of ragers tbh. Competitive ones (like me), general ones (people who just freak out all the time because they always care about winning), and then SUPER DUPER AWFUL EVIL ONES (who intentionally feed and stuff like that in response to having things said to them about their game play). I really think most people who will get restrictions are the first type, I really doubt they will be polluting your games. I am at a much lower elo than I was last season because of how frustrated I get in ranked this season. This is a good addition to the league of legends game.
I'm toxic, this is helping me, I don't talk in normals at all. You really don't have much to worry about. Hopefully ill stay chill this time.
Good luck.
p.s. I already know theres going to be a flood of people saying "all ttoxic kids are the same you all deserve blah blah. rito doesn't want you here " you're part of the problem. You should also look at yourselves as well.
