This might be solved with a “pause and report” option which unilaterally pauses a game and reports it (for stalling, score cheating (anything else? just things that can happen at the end of a game and prevent the game from ending naturally)), with the game staying paused until a mod checks it out and either declares it a win for one player or the other, or annuls it (the former is an option because the game is only paused, not ended)
In this particular game, Brendix was handicapped in dealing with the stalling, because he was playing with a ruleset that does not allow infilling to resolve scoring disputes. If he had been playing with NZD rules, then he could have just defended everything until it was pass-alive instead of trying to pass the as soon as he could (once it had become clear the opponent wasn’t), and then passed thrice to activate the feature on his side
I think either one of these changes, one of them in the complete control of Brendix, would have prevented this miscarraige of the Antistalling feature
