The #1 spot is occupied by someone who has been playing 1123027 hours, or since the 1870s, producing an average of 1200 babies an hour. Only 17 of these miracle babies have died.

The top 13 slots are occupied by the same user name

The top 16 slots are occupied by users with populations above 92 by several orders of magnetude.

If these are test users, clear 'em out. Send 'em to a page on your test server.
If these are regular users who've cheated, weed 'em out.
