Think before you flame. Don't stab an already bleeding wound
99% of toxic players flame because they don't think before typing and don't even bother understanding why their 'victim' is playing that bad, in their opinion. Change my mind. I bet you can't.
People, really, stop flaming, OK? I know calling your 1/23 midlaner a 'B5 idiot', but stop. You know NOTHING about the reason behind their seemingly horrible plays.
Maybe that 'inting' midlaner suddenly had a ping spike and now, despite being called 'idiot, dumbass, troll' by you, he's still trying to do his best and hold his tower even at 800ms. He knows he is going to die because he can't dodge anything, but he's doing his best. Even if he keeps giving enemies 59G, he's still protecting your damn base.
Maybe that inting midlaner is playing against a booster. I have played countless normal games with my D4 friend, he enjoyed stomping Goldies like me, and this is NOT FUN. Maybe those Goldies were really good for their league, they were trying to do their best, and then my D4 amigo comes and ruins their game. If your teammate is 2/11 that doesn't mean he is bad. Stomps are real. Smurfs are real. Counterpicks are real. So delete your 'go afk idiot feeder' from the chat, please.
Maybe your inting midlaner is really trolling. OK, I DO ENCOURAGE YOU TO REPORT HIM AFTER THE GAME, write a ticket, whatever. But just don't flame, okay? You DON'T know for sure if he's trolling for fun, or he simply had such a good game where he played so damn well, then someone on his team decided to sabotage his carry plan and he lost. A lot of players troll out of tilt, because they're too angry to try their best after doing this and still losing. Inting is a horrible revenge strategy, but still, don't judge. Report them, don't flame. You are just MAKING THINGS WORSE.
TL;DR: STOP FLAMING. THINK BEFORE YOU PRESS ENTER. You never know the reason behind your teammate's mistakes.
