Chess.com is in a constant struggle to contort its system in attempt to address the problem of unresponsive players, without admitting that it is wrong to restrict 1st move aborts.
I can see assigning chaos points for Black aborting on move 1 of Chess960 if he/she doesn't like the position. That's naughty. But normal chess? Please.
....they are not even sanctioned games people. The rating you have here is as useful as monopoly $. Think ! Players use engines, softscript in nuances/advantages, verbally assault, obnoxiously abort, etc. And guess what ? All for free !....and all incognito !....anyone taking free online chess (you've opted to pay) seriously is, well....(left palm of hand contacts forehead....eyes roll looking for brain....)
.....and Monopoly money = Bag of Groceries....
FYI, I timed it today. The current auto-abort time out is 1 minute, which is not entirely unreasonable, but I actually had two opponents auto-abort in a row today. I'm very tired of these idle opponents.
There are settings, but none are related to aborts (http://www.chess.com/home/livechess_settings). Aborts are controlled by chess.com.
