Punishment against Deliberate Time Wasting

Recently I met a couple of players who, when they realize the defeat will be a certainty, leaves the game with a large amount of time on the clock instead of resigning. I believe they do this to deliberately waste their opponent's time in an attempt to "get their revenge". In my opinion such behavior should be punished, as it is simply against the principle of sportsmanship.

Have you encountered such players? What can we do about them other than reporting?

You can check the game history of this players. If they do this all the time, then simply report them and copy the links of the respective games into the report.

If you don't want to report them, you can also just block this players to avoid facing them again.

You can't post in the forums yet. Play some games!
