Remove a game I won from rating increase

Is there any way to remove or decline the rating bump I got from a game where my opponent resigned after 3 moves? (no idea why, his opening was fine, maybe he just wanted to quit, but it was a daily game so kinda odd). 

Lately I've been frustrated with the chess.com rating system because about 10% of players just decide to resign or abandon for whatever reason, which increases my rating when it really shouldn't - so if I play opponents at my rating I seem to lose 75-80% of the games. Either I'm getting worse, opponents are getting better, or the rating system adjusts too slowly / gets unfairly influenced by tossed games.

I understand not being able to remove a lost game, but surely there's no harm in declining the rating increase from a won game? (would allow me to correct games that I didn't really win)

No, there's nothing like that. After a few games any rating gain is going to have no impact on your later rating at that point anyway.

I don't think there's a way to do it. Just keep playing daily chess, and you will find some decent opponents, who don't lose on time, don't resign and don't abandon

If you remive your points from that game, then you will keep playing these guys who abandon etc, and you won't find interesting/decent opponents

Roger that. It happens in blitz and rapid games too in the 1000-1200 range. Sometimes people resign a winning position because they thought it was losing when it was definitely winning. Sometimes it feels like half my "wins" weren't real wins. I guess that is just part of playing at this level.
