Recent spike in trolls/leavers?

(Let me just start by saying I never complain about this stuff) So I've recently seen a spike in trolls/leavers and as a matter of fact, my last game my WHOLE TEAM left, lol. I'm just curious if anyone else is encountering anything similar (Above Plat 5^^). I've attached a screenshot of a guy whose only goal is to mid or feed, for example. And this isn't a one or two game thing (Believe me I wouldn't be here if it was), it's happened 5 times in a row now, which I find really strange.

Soooo, anyone on the same boat?
