Kick over your King!!

Is there a trend forming on Chess.com? 

People playing on in lost positions. I've had several games of late where my opponent has kept on playing after being down by a piece or more. 

What is going on? I'm sure this is a recent development. Or maybe my feeble mind is showing its ability to forget things in a new way. But seriously, if you are down a piece in a lifeless game, do us all a favor and kick your King over so we can all move on.
