And I say this again. On Chinese Go servers there is an option of 'force scoring' if the number of moves exceed a certain, unrealistic amount. On QQ WeiQi this threshold is currently 375 moves on 19x19. By then the game will be forced into territorial scoring without consent of the opponent.
Leaving aside extremely small number of cases where a game will exceed 375 moves in a meaningful way, I strongly believe this kind of feature is the life saver that many players are looking for.
Let's face it: moderators aren't always around 24/7, they take time to process the query. Minutes if they are online, an hour if they are not. If OGS is to grow, it is inevitable that the number of incidents like this will continue to rise. I see no reason to not have this feature.
