Appeals Committee. Disputed situations in tournaments.

As I see it now, a more optimal solution would be to add the user to the "Blacklist" and award them a "Black Mark." Tournament organizers would then have the right to include in the rules of upcoming tournaments a clause stating that "Users with Black Marks cannot participate in the tournament." A major advantage of the "Black Mark" is that it is displayed in the user's profile, which already serves as a warning. Another option could be to permanently display the "Black Mark" and then replace it after a certain period with a "Gray Mark," which would allow the user to participate in tournaments that they couldn't participate in with a "Black Mark," while the presence of the "Gray Mark" would still caution users and organizers. The very presence of a "Black Mark" in a user's profile, as I think, would give the player an incentive to play fairly in order to get rid of it, even if it means replacing it with a "Gray Mark." It is even possible to consider an option for completely removing the "Marks" after an even longer period, if the player finally gets rid of the bad habit of violating tournament rules.

Testing a new social system – which is what the "Black Mark" system is – should never be done with full force if there is even the slightest chance of failure in its implementation...
