No matter what you designate as the premise before going on the leader board, someone, somewhere will always find a way to cheat to get around it.

There's just no way to keep all the cheaters off the boards. The Tech points or whatever set up would be violated just as easily as that one person with 50000010 elders. S/He would just edit the game file to fit in as they've already done. Warpers could probably be dealt with by limiting the time frame from date of release (which would drop off the person that's played for months, and definitely get the one that's played for 136 years off there). Unfortunately, the hacking cheaters are not dealt with quite so easily.
