when the opponent goes martin mode

Just now, I was playing some blitz and tilting lots and lots of ratings. Suddenly, when I was about to tilt below 1900, I played this guy called @Alvaroo12. I had never heard of this guy and was very confused as this was our first game: https://www.chess.com/game/live/83872301025

He proceeded to rematch me two more times. I accepted out of confusion, as I was busy wondering what the heck this guy was doing. After two more games, I gained a cumulative 28 rating off of him. After checking his games, I found out that most of his games were normal. Those three games and one game before that followed the same logic, as in the game he played directly before this one, this happened: https://www.chess.com/game/live/83872209305

My original hypothesis was the classic "i gave the game to my little brother" but he was playing so quickly and so accurately terrible (not even taking a free queen right in front of him and blundering queens on f6 and f3 all the time) that I have no idea what even happened. 

Someone provide some insight because this is just the dumbest thing I've witnessed firsthand in a while.

High chance. The last time I lended my girlfriend my chess account and she tilted my bullet rating by a 100.

Moral of the story? Trust yourself only.
