Damn. He be salty.
I'm not one to get behind trolling or the usual immature behavior that can be prevalent in gaming, but like he said, "tea bagging" is old shit. It's not as common as it once was (outside of the actual mission for tea bagging in Ghosts) and it's almost quaint to see it when happens anymore lol The guy isn't exactly wrong, but writing an article about tea bagging in 2015? Polygon be Polygon.
I'd actually place tea bagging much lower on the scale of "poor gaming sportsmanship" than he seems to place it. At the top, it's people talking shit on voice. That drives me nuts. Below that, I'd say teamkilling. Then it would be talking shit on chat. Then probably a half dozen other things. Then there would be tea bagging lol
