Reporting Duos

Most people in LoL have their moments where they snap and argue with a player instead of muting them. I just had one of my moments about 10 minutes ago with a duo. I know most people don't care about 3v3 ranked flex, but I thought I'd bring it up. The game had started (I missed the first minute because I was in the bathroom) but then that's where it began. From the moment I got into lane, two players (EDIT: DIDNT SEE THE RULE ON NOT NAMING PEOPLE) both thought it would be a good idea to say "we lost this game when you chose twitch and afked" (mind you I hadn't even missed the entire first wave). I was against a Tristana in lane and I was playing as a Twitch. As Tristana can easily out trade me for damage, and I don't really do too much early on I was trying to keep my distance. I fell slightly behind on CS and then both of the teammates I had started harassing me telling me that I sucked at CSing and that I shouldn't even be silver. To be honest I found it kind of funny that the person saying that was G5 with 0 LP... Anyways, after repeatedly missing skillshots, leaving me to die, and generally trolling me, my teammates then thought it would be a GREAT idea to start taking the things that they were saying, and say that I said it to the other team. I'm getting tired of constantly you have parties of people who don't like someone so they start telling the other team made-up things in attempt to get you in trouble. Yes I argued. Yes it was stupid. No it was NOTHING like "kill yourself you're garbage" It was mainly like "you can't even land your skill shots and youre calling me bad" "You're on the barrier of falling down into silver, and youre calling me the silver trash" "I have more farm than you and I came back late AFTER you harassed me for having half of your farm" I guess this is more of a rant than anything, but I guess I'll end it with: What can be done about a group of people who out number you lying to the other team in attempt to get you in trouble? If it is just you reporting them, they won't get in trouble. If the 2 people + people on the other team report you, then you are likely to get in trouble.
