A compendium of OGS's terrible scoring system confusing beginners

There is a very widespread mistaken belief that one does not need to fill in dame when playing with Japanese rules.

This belief is supported by the official rules:

If the players agree, they may fill the dame and add other necessary stones after stopping the game, in which case these are not moves as defined by the rules, and need not be played according to the rules.

So filling dame by playing actual moves (ie. before passing) is not needed (unless there is disagreement). And in online games (without a dispute) the counting/confirmation procedures after passing are skipped/automated of course.
