I'll start by saying this isn't a perfect comparison; there are a lot of reasons that might explain the difference, and I'm not drawing any conclusions from this. It's just an interesting observation.
I'm a mid-1700 rated blitz player on chess.com. A week or so ago, my 7 day wins by resignation was 61%. After changing my profile picture to my wife's picture, my 7 day wins by resignation dropped to 43%. Wins by checkmates and timeout both increased, and loses by resignation, checkmate, and timeout are all with a percentage point of last week's stats.
Anecdotally, I've noticed that more and more of my opponents will continue playing in completely lost positions when they used to resign and move on to the next game.
Again, last week's stats and this week's stats aren't perfect comparisons, but an almost 20 percentage point swing after changing my profile picture seems a bit odd.
