I know that time is a part of the game, and I have won games by flagging people myself.
But the case in this thread is the clearest drawn position imaginable. The position is even so much of a draw that there is no imaginable theoretical possibility for any moves to be played which do not lead to the result of a draw on the board.
There is a technical solution that would have solved the problem in the game with which the thread was started:
Implement the possibility to cleanly input multiple premoves (i.e. a sequence of moves I will be playing no matter what the moves of my opponent will be). Then it will be no problem to enter 50 moves consuming 0 seconds in such a position. Removing any incentive for an opponent to try to win by flagging.


Therefore, you displayed decidedly bad form by disclosing your opponent's real name, not merely his username, when you accused him of "extremely bad form." Telling us your real name in return does not really rectify this. I don't mean to sound blunt, but in the future, please be more sensitive to your opponents.
Pianist, would you be so kind and browse through redhands "live chess" archive.
You will quickly note that he did not use the real name of his opponent.
It is also a custom here to check the facts before posting something that might be considered an accusation.
The custom of checking facts normally applies when those facts are not provided (such as the OP's actual final position). But when the OP gave a name, I naturally took him at his word. I shouldn't have to hunt down every iota of information provided to verify its accuracy; at some point I should be able to trust the OP to actually know what he's talking about. If you were trying to embarrass me for not checking my facts, you failed, because that was not my fact to check. If any embarrassment is to be had, it is by the OP, who apparently took a random guess at his opponent's real name and got it wrong!
You'll also notice that I still haven't checked to see what his opponent's real name is, whether anybody got the name right, or even if it's listed on his/her profile. This is because I don't have to and don't care to. This is not my responsibility.
But getting back to the actual subject at hand, the clock is part of the game. In the OP's game, the position is locked and neither King can make any progress, which is puzzling indeed. I think OP should take this up with the support staff, as they may be able to change the result, if it should indeed be a draw (and that certainly appears to be the case).
But using the clock to one's advantage, particularly when it becomes a liability for the other player, is rarely (if ever) unacceptable. In this situation, the player with more time generally starts moving much faster, voluntarily taking upon himself a risk of making a game-losing blunder. That risk offsets any alleged unsportsmanlike conduct.
