Jonty,

The problem is that they exploit that is being used by the cheaters is 'out there'. All the new versions do not contain this exploit, but some old ones out there still do.

I have been removing 'cheaters' manually from the leaderboard--I know it bothers people. I don't have enough infrastructure on the leaderboards to ban anyone from it, though, but I am considering other solutions.

Incidentally, we don't make any money by running the leaderboard, so I don't really see how we're after 'the money'. We added it as a way to allow players to compare how they are doing, just for curiosity's sake. We plan to continue supporting a leaderboard with the next releases because most people like it. We are also trying to learn from what is not working with this version of the leaderboards.
