"4 Man Premade got me banned"
No they didn't. You are responsible for your actions and if you got banned or punished it was justified. If anyone in their Premade was toxic report them and everyone who broke the rules will be punished.
I'm just so tired of people blaming 4 man's when the report is based solely on your chat and your chat alone
Remember, 1 = 9 when it comes to reports
Edit:
I see all these comments saying "4 man's make you say reportable things or thet feed" well you don't have to say them and if they are a 4 man then you aren't playing ranked so let em feed and report them all at the end of the game. You're already stuck in game with them no need to get yourself punished by submitting to them or retaliating.
And for the comments saying key phrases trigger reports. As long as it's not repeated I've at least never had problems with punishments, I've even said "Stop being a bitch Nami" and muted her after she was pinging needlessly and being toxic.
Your actions are still on you, let the toxic people out themselves and report them, don't drop with them.
