Even when 'winning badly', there is an obligation to wait until the game ends before leaving the site (or closing the game window). Same deal if you were attending an 'over the board' (in person) tournament.
Accidents will happen. By 'paying' the price, perhaps you'll be more careful next time? If there were no consequences for such inattention or accidents, this might happen very often with many members, to the annoyance of their opponents. The site would become less popular and risks a mass exodus to one of the many competing chess sites out there.
It would be nice if the system did not permit us to start another game if we're unable to do so properly for our membership category.

I was winning badly and my opponent disconnected, and then I accidentally closed the window trying to minimize it, and the system resigned automatically for me even though it was my opponent's turn! This is HORRIBLE...must be changed.
On another note, the system should make it impossible to play multiple live chess games at once... i thought i had won a game when my opponent disconnected, and then i started playing a second game, forgot about first game, and with one second left my opponent logged back on an made a move and I timed out...horrible...but i guess that's my own fault
