From unpleasant experiences with cheaters who refused to accept the score in both the old and revamped OGS Scoring Mode, I have some points I would like to make and suggestions on how to fix it.
In the old system when people refused to accept score or only accept their intentionally messsed up scoring (e.g. marking live groups as dead), the only way to solve it afaik was to call a mod AND leave the game open. The moment you closed the game first, it would indicate to the system that u left it which would trigger a loss for you.
In the current system, there is a Scoring Mode Timer to prevent non-results from unwilling participants, but this forcing of result can also resort to exploitation by forcing your opponent to constantly edit the scoring to keep the timer moving to prevent the opponent from getting his desired erroneous scoring. So even if you call a mod, you no longer can simply leave the window open till a mod arrives (usually an hour or more), you have to actually play 15/20 second (forgot the exact duration) Scoring Mode Byoyomi with your opponent for an unreasonable amount of time till your mod arrives.
When a mod does arrive eventually, from past experiences in both pre-revamp and current systems, the mod cannot (or claims to) give you the win but at the most annul the score. What this means is that, when a player does not want to lose, he can simply use such cheap tactics to at the very least “draw” and not affect his precious rating while the other deserving player, who devoted at least half an hour or more on average to play the game, is cheated out of a win.
For those lazy to read, in point form on scoring timer problems:
Old System - Have to not leave game before opponent leaves, while waiting for mod to prevent auto-loss. At which point the best you can get is an annulment from mod.
New System - Have to play sudden-death “byoyomi” Scoring Mode Timer game with the opponent till mod comes. Can no longer leave window open and do other things. Annulment is still the best you can hope to get.
Suggestion: Lock the screen with a BIG pop-up stating that the game has been locked till moderator review. I know this could potentially mean a huge backlog of reports to clear, but I don’t see any other way to remove this exploit. A warning that wrong reportings that waste the mods’ time would result in bannings, should cut down the downside to this though.
How to verify claims: Simple, just give the win to the player that actually has the bigger territory. If the one reporting is the one with the bigger territory, no issue. If the one reporting is the one with the smaller territory, ban him, for inconveniencing everyone with false claims.
