This thread (
https://bitcointalk.org/index.php?topic=1850855.msg57682083#new) is full of new accounts just copy pasting same message.
Maybe the owners/thread OP needs a different sort of mechanism or a form to reward the users who won big on that site.
I don't see any reason to spam this forum with new accounts just to claim a reward.
Not sure if this has been discussed before, found it really odd.
