Draft Pick: Chat Restriction/Ranked Restriction Question & Tips please.

Hey everyone. I'll be the first to admit that I am disgustingly toxic. About a week ago, I decided that I wasn't going to contribute to the negativity that you see in each and every game that I play. So I've TRIED to work on it; it's a work in progress...from googling tips. However, I've gotten a lot better...I'm finding that I mute people a lot. So, now I'm playing out my ranked restriction, trying to keep to myself. However, my question is more along the line of if people who are toxic are grouped together. Since I've been working on not being toxic; and playing only Draft Normals...I've had trolls and toxic people in every game..including a queue of 4 people together who all reported me because "They thought it was funny and felt like keeping me chat banned LOL" as they put it. I'm not sure how the league chat ban system works...but there's no way I can work on being less-toxic if every game I play RECENTLY, someone is afk, or really mean. Even when I mute them.

This morning I played a game with an Annie..she was toxic. So I muted her, without even telling her I did. She must have figured it out. So she followed me around the jungle, trying to KS my camps..and then dying in lanes I would try to gank, intentionally.

So to sum it up. 2 things. 1.I need some more tips on how to work on being a more positive player in League...Because sometimes it's really hard for me..maybe I'm mental..who knows. 2. How do I get through playing these games in drafts so I can go back to ranked...whilst dealing with all of these negative people who clearly also have chatbans?
