They are having trouble figuring out ways to keep simuls for counting as points. On a scale from 1 to 10 in difficulty, this is about a 1. Does anyone really think there's a way to stop super clever people from figuring out ways to collect trophies. I'm not even sure they can stop a dumb bot from playing since their anti-cheat software is designed to detect best-moves from high rated bots. If you throw a 1500 rated bot in there, I'm not sure they're capable of detecting it.
Nothing immediately comes to my mind for the psuedo code of how to identify which games are simuls and which aren't, other than to have some kind of flag set for when seeks are initiated during a game... and since they don't have something like that in place, trying to make one would affect all sorts of interconnected code.
There are some extremely simple things they could do (but don't) to catch e.g. sandbaggers and people making multiple accounts to boost their rating... but, at least in my mind, detecting simuls wouldn't be that simple.
a blitz player going from 1400 to 900 would get thrown out, maybe a 1900 going to 1400 could happen
What's the difference?
