A compendium of OGS's terrible scoring system confusing beginners

As often happens with the passage of time, there seems to be widespread forgetfulness about previous discussions on this subject. See Autoscore is still overriding players’ skill level

The current autoscore remains defective in at least two ways. The autoscore bug—when closed territory is left unmarked—which began roughly in August of 2020, still exists. It was greatly reduced by the last autoscore revision, but still pops up occasionally (e.g., sev ra vs. Fard, or Zeraora vs. GeorgySmolyar).

More serious is the issue that was the focus of the cited thread, and which still occurs now and then. That is, where the autoscore scores the game based on an AI variation rather than on the basis of the board as it stands. Recent examples: jaelgraham51 vs. KingDe3, Partida amistosa. This is a violation of site rules because it constitutes AI assistance to the player who shouldn’t have won (because he didn’t know the tesuji). Until this is fixed, it means that a player not only must beat his or her opponent, but must beat the AI autoscore.
