There are huge numbers of people accepting invites and automatically deleting them. I know it pisses me off, and I am certain it pisses you off, so how is it that there is no consequence for these people?
They understand that they are accepting a game within a time limit that their opponent has set, and they know that their opponent will move within that time, so why is it that once they have it they will wait 2 minutes, then delete it?
If they don't see that person online, and they wish for a faster game, they have 4 options, they can join a different game (one with someone online), they can create their own open invite and hope someone accepts, they can challenge a friend, or they can reduce themselves to waiting the 2 hours for their original opponent to make a move.
With these options documented I see no reason why games should be deleted, except for someone absently clicking their mouse at the wrong name (but that itself is a rare occurence), therefore why should these deleters not be given some sort of punishment to deter them from deleting again?
p.s, How do you indent on these messages? I tried using the tab key and just adding spaces, and neither work.
