It either means, they don't want to play with your rating or don't want to play as black ;)! Chess.com tries to limit people from aborting matches by making them lose points in there rating for aborting more that 2 times a day ;)
why do people....

Or, more specifically, they don't want to play Black against anything other than 1.e4 or 1.d4. I get a lot of quitters when I'm White, but they don't quit until AFTER I play 1.Nf3. I get a lot less quitters when I play 1.d4.
In my experience (with my old account) it means that people start games and don't have enough time to play and don't want to "lose" so they just leave. Very annoying.

That's surprising, as I'd expect if you're playing other people with high ratings they'd know how to respond to the Zuckertort opening. I just play 1...Nf6. Do you think that's a good reply?

I think anything that doesn't hang a pawn is a good reply. I use d5 as my reply, and if they do d4, then I do c5.

back to the tpoic, though, I think that in my case it may have to do with my nationality, (US) even though I don't instigate opponents like others, and it ends up being a sterotype that harms others. Another reason might be because I play d4 and people prefer playing e4. I wonder if more people abort against c4, though?
do you know what i don't get. when ever you are about to start a game the other person exits off the game. why do people do that its not cool
what do you think about people who do that?
