I learned a long time ago, getting my butt kicked in chess tourneys, that the honorable thing to do was resign when the game ending was obvious. Even then, I saw people who were obviously going to lose sit there and make the opponent sit there while his clock ran down. To me, that's the SE4 equivalent of not submitting a turn and forcing everyone else to "watch your clock run down".
I know RL pops up sometimes (Nodachi and Gecko come to mind) but it's also obvious that RL wasn't the problem when you see the same guy active in another game.
I don't like quitters like that but I try to take them in stride. No point in "having a cow" as Bart would say
