Can you dispute being chat restricted?
My account is literally filled with keys from player honors, I'm always getting keys for being a positive player. I had a game in which my adc flashed and healed into lane at 100% hp 2 minutes in, it looked like trolling so I typed "Wtf?" and the Jinx responded by calling me a "r***ard", flamed me all game, refused to farm if I was in lane, spam pinged and ulted at me every time it came up.
Enemy morgana typed "Jinx tilted?" and I typed a little in all chat with "Ikr, did you see the flash heal?"
This was about the extent of any "negativity" i can possibly think of, I'm just not a flamer in anyway, I'm always a very positive player, I play support and always encourage my team. I got reported by Jinx, who told the enemy team to report me in all chat too. Ironically I just got chat restricted for a game where I got flamed all game and didn't flame at all back.
I get maybe the best thing is to not reply at all but I definitely wasn't toxic, I didn't spam pings or insult players, someone even called Jinx mentally ill in all chat and I defended this by saying that's going too far. Pretty disappointed in the system and wondering if there's a way to file a dispute, get an actual person to look the chat over and see I was being a calm nice person considering I was being called all sorts of offensive slurs all game.
