Too many children or just really unlucky?

I have gotten to my promos to Gold 2 four times in the past week, and every single timeI get to the third match I have gotten a teammate who starts to feed on purpose before we're even 10 mins into the game.

I am not even slightly over exaggerating with those numbers, every single third game (since I have had to play 3 all four times) someone on my team has fed on purpose. I literally do not even say a word, 3 of the times not a single person said anything negative at all! The fourth it was actually the feeder talking shit to everyone and we all just said "ok muting you now" and he then started to feed cause we muted him..... The asstwats just decided to feed cause they died twice in 10 mins, or their supp took a kill, or some fucking childish nonsense like that!

So I'm just stuck wondering, am I just seriously THIS FUCKING UNLUCKY!? Or is there just seriously aht many childish pieces of shit playing this game?
