Genuinely Confused

I can't control if someone I get along with joins the game separately from when I do with no intention to join and team up beforehand and get targeted. A premade is joining the game together intentionally to align not happening to he in the same game with friends ..the site is not that big you can't just avoid playing games with friends. Also I genuinely take each game very individually so I'm bound to work different folks but not given the chance because they see me and insert several friends names. Rant over lol.
