Ok I have now been a member for about a week and see what you all mean about cheaters, whilst most people love to get their 15 minutes of fame & get their name on the board it seems to me that if you are one of the "lucky" ones that gets 51 or even 52 elders you will stay on the board for ever, even if they quit the tribe & start a new one.
One option could be if players dont update their stats every so many days then they drop off the board, also the board could be extended with a button to view the next 100 etc. I appreciate it won't do anything to stop the cheaters but if it was set to show all players who had acheived the 50 elders & 16 puzzles/tasks at least the honest people would get the chance to say "I made it"
