Trolls in Ranked

Okay im from oce and our server is filled with trolls from top to bottom but i just played a ranked game where our yasuo went 0/5 in 11 minutes to mundo top. He started yelling @ me for not ganking enough (ganked twice by that time all while trying to farm with getting invaded); honestly our team was good. it was 28 min game, our vayne got a penta @ 20 minutes and ended with 17 kills. So from that 11 minute mark, our yasuo left his lane and started farming my whooole jungle. That's all he did for 17 minutes, from the 11 min point till the game was over; farm my jg. He went from 0 cs to 186 cs by farming my jg. I of course, fell behind because by the time a team fight is finished and I go to farm, the whole jungles are gone including enemy. I ended at 68 cs with nidalee (lol the horror) and yeah we lost cuz yasuo is a dipshit. his final score was like 0/11

such bullsht smh. I'm a bronze 5 girl gamer so im not like that good but cmon, there's a difference between giving it your all and failing, and being utter trash at the game, dying 5 times in 10 mins and intentionally feeding (yeah he did admit he was intentionally feeding, he just wanted to farm my jg to make sure I dont get fed).
