How is their account even active?

So last night I had some free time after my jog, and I thought "hey I've earned some ass-sitting time, a few games of league sounds fun!" Wrong. Lost my first game, whatever. Shake it off. My next game, we got off to an early lead. I was playing out of my mind, and so was our Zac. His ganks were on point every single time, and Riven was doing well too. Then we realize, why the fuck are we behind in gold? And then we see what our adc is doing after their second consecutive death. Our Ashe literally ran straight down botlane and gave the enemy botlane kills until she was 0/10, then when we grouped mid we thought a super fed Yasuo, riven and Zac could carry the game. Wrong again. Ashe ran it down mid until she had 0/24 KDA or something like that (it's the most recent match in my history for reference). And we played our hearts out and tried the best we could, but over 20 free kills to the enemy team just makes the game unwinnable. And just to make us more upset, the Ashe joined the post game lobby and immediately started posting "hahaha get good %%%s" and "lol haha guess I lagged a bit." I hope you enjoyed yourself, <removed by moderation>. Because literally nobody else did.
