I won't talk about individual users who get marked as cheaters or sand baggers or how we do it. Both because it would violate our rules on public shaming and because it would advertise our cheat detection methods.
I will however answer questions about how lichess works:
- Tournament results CAN be changed afterwards if a sandbagger or cheater is found.
- It is true that cheaters are more likely to be caught when they play against streamers because we are more likely to notice. I don't understand what we are supposed to do about this. Should we NOT mark the cheaters when we catch them to make it fair for non-streamers?
- It is true that players getting banned during a tournament could affect certain players more than others. This is absolutely necessary. Sandbaggers are often trying to help one player win a tournament. Sometimes players alternate between cheating and sandbagging. The cleanest solution is to just remove their games from the final score.
