People in Solo Q

Okay, so this Nami fed this enemy ADC/Twitch 10 kills and then afk's in fountain, as does the J4 on my team. I ask the enemy team to report them for feeding and afking, yet somehow, I'm the one getting reported, I'm toxic and I'm salty. I really don't understand this community. But when these people are on their teams, they say the same things I am. How about a little understanding and roll reversal. It's pretty ridiculous.
