Not the most toxic case I've ever seen, but your attitude is quite negative, and you're a dick to your teammates. Definitely understandable that you got a Punish for this.

Just learn from it, and stop being a complete dick in your games. If you have to, don't talk unless you need to call mias.

Most of my ingame chat consists of "gj", "ty", "mia", and objective discussions(like start buffs for junglers, or dragon/baron/towers later on). There's no real reason for anything beyond that, certainly not telling teammates that they suck.

Just because there are only 4 games in your case doesn't mean that you were only reported in 4 games. I believe Lyte once said that it requires "Dozens of reports" to even get in the Tribunal to begin with.

what sereg said dude you're a bit negative which is why you got reported, just settle down

Just because your case is 1 game 1 report doesn't mean that you've never been reported aside from that game. I'm not sure how the Tribunal decides which games to compile for a case, but unless something has drastically changed in the past week or so or Riot is flat-out lying, your case is not comprised of every game you've been reported in.

Just because you are shown one report does not mean that there are not more behind it. It would take a long time reading through like 15 reports, that is why you only get a selection ... probably random as well.
