Playing duos with pingmeiquit

This morning I was matched up on duos, for the second time, with a player who goes by the tag pingmeiquit. I confess, I didn’t read the name or pay attention to it until the trouble started in both games. In our game this morning, I pinged a question mark over a toon in the tavern to see if he wanted it. He immediately stopped playing, though he didn’t quit. I started clicking on his board to figure out what was wrong. That’s when I realized it was this guy again. He became agitated by my pinging an retaliated by pinging on every pingable icon on my board every turn for the rest of the game, which he did not quit.

Has anyone else had to deal with this ?

Why would someone with an aversion to being pinged play duos ?
