It depends on what is happening in the game of whether or not to accept something like that. Like, if I'm top and 0/5 at 20 minutes, I would have already told my jungler to abandon top and help someone else because I'm not going to be useful to the team since the worst thing that happens is the enemy top kills me and hardly gets any gold at this point. The most I can do is try and stop TP plays and make taking the tower inconvenient, hopefully being able to be a bodyguard for a hypercarry. If I can act as a meatshield for someone who can carry and eat skillshots coming at them, it's better that I die than they do. Alternatively, if it's just because I missed a few skillshots and I'm still doing well overall (be as realistic as well; 3-7-4 isn't good so don't kid yourself) then I ignore them and try and be more careful.
Probably not the answer you're looking for, but you do need to have thick skin and a strong sense of determination to play. Even as caustic as my personality is, playing from early(ish) season 2 to before the mage update in season 6 when I quit, I haven't even received a warning, let alone a ban for anything. In fact, I hardly say anything at all. I won't lie and say I don't lose my cool once in a while and go way off the deep end, but it's mostly a silent game of enduring the ignorance of the stupid and the clearly inexperienced attempting to teach the team how the game apparently works, like how 4 people at half health should start Baron while all 5 enemy members at full health are literally 1500 units away was the right thing to do...for reasons unknown to everyone but this "genius."
Again, it's not what you want to hear, but you just gotta deal with it, and if it's doing things to you mentally, take an hour or so break and in my case, give your blood time to stop boiling before going back.
