Are you talking about people who don't start or the people who walk away after hanging their queen.
In many games where my opponent rage quit, I have just resgned and moved on.
I think people who don't start the game desevea loss. I would have quite a few losses this way, but if the game has started it's pretty unfair to the person who is ready to play. Some times I will get matched with someone who will abort several times in a row.
I agree. It seems like this practice is getting more prevalent. The idea of forcing a response to a "win button" like RSenekal suggested is a good one. Typically, when some one abandons a game on me, I look at their profile and see a list of people complaining about the same thing in other games.
It seems like Chess.com is losing its quality. I've been subscribing for a while, and may start looking elsewhere if this gets worse.
At least, for subscribers, can't you offer that kind of automatic win button?
