Hide cheated games #110

Ideas:

Mitigate by excluding provisional ratings from top games
Blacklist of users on display (ornicar/lila#8378)

Cubox commented 3 years ago

Unsure which would be easier to implement, but you could also calculate which ratings were the highest ever obtained by legitimate players. Then block all games with ratings above that to be displayed. You could also give a pass for titled players from that.

This would remove the insanely high ratings games from top games. Top games for a board without any moves would be from leaders in the TC in question.

Yeah I knew something was up when they were showing "3500 rated" players

niklasf commented 2 years ago

In the recently deployed version, "top games" are no longer the absolutely highest rated games. Instead, they are recent games from the highest rating bracket. So insanely high ratings reached by manipulation will no longer stick to the top indefinitely. I am tempted to say this is good enough.
