Arcade Anti-Cheater Mod

Board: 3.x

Purpose:
If your board is a scripting/coding board you probably have cheaters using your arcade. They are people that use memoryhacks/colorbots, and believe me, people do cheat. This hack is to clean up scores. Before, if you wanted to remove a score, you had to create your own mysql query and even though the score was removed the highscore still showed up as belonging to them. This process has been fixed by this hack.

Functionaliy:
- Remove all scores from a user
- Remove a users highscores
- Fix the titleholders/highscores

There has to be a way to know they are cheating, does anyone know how to tell or if there's a way. I hate to remove all of someones scores just because "I think" or "assume" they are cheating.

If they score higher than the max score for the game, you know they cheated.

There is no way to know whether they cheated/are cheating in a simple arcade game.
