It's another nice move, Roobet team. I understood that sometimes teams have to make decisions to adjust rule when cheaters come in and compromise the system. I am not Roobet team member so I did not know what actually caused your decisions to make rule adjustments, that affected the win of dkbit95 but maybe at the time the time implemented new rules, they did not realize that there are winners instantly affected by that adjustment.

In campaigns, companies and managers emphasize that they have rights to change rules at any time they want. As the others said, new rules should only be applied with new rounds, the last round before rules changed should be applied with old rules and people who satisfy requirements with old rules should be paid. That's all.
