freebitco.in is a website that may have more users than bitcointalk overall let alone having all their users here
This is an exagerattion unless there is a valid proof for the exact number
If they wish so, or if the public really wants to, they could do something like that for rolex winners as well, just pay them some extra money to come and write here, hell even do that for lambo winners
IIRC wasnt the lambo winner used to post in this thread? Anyway there is always that few players in every casino that win the mega jackpot, lambo or any huge grand prize from the site but that user barely chat or show himself up so it doesnt really matter. People can always choose what they want to believe, including wether they believe those lucky winners do exist or not
