Found this gem on the Reddits, What is your opinion on "is it toxic or not to..."
"Is it toxic? I have int-ed over 30 deaths in the last month due to ppl taking cs." "This includes the "support" malphites that max e and build ap and one shot the waves in lane phase. Also, the people that see you ping "on my way" to catch a crashing wave as adc, and they either Teleport across the map or leave their jungle camp halfway through to go take it all before you get there. I feel like that should be report-able, but since it isn't I usually just die 3-6 times after that and I don't try to lose, but I don't try to win either. This is the only time that I ever play like i don't care about winning, as there is nothing worse than getting stomped and seeing "adc just farm and be safe" only to have that same person run into your crashing wave and ult it as vel'koz and then "thumbs up" emote you.
So is it toxic to do what I do in those circumstances? I don't just run down mid afterwards, I usually just blind push a lane until someone kills me...over and over. Plat 2 btw."
