I myself have been playing on freebitco since 2016 and till date, I've never gotten that number, and neither have I seen anyone who has or had, not on this forum, and not outside the forum.
Same goes for the weekly lottery and every other forms of giveaways on that platform, like the lambo draw and all.
The lambo contest is one that I have been mostly interested in to see who the winners are, and since I joined the platform till date, not one person has ever come to this from to declare him or herself a lambo winner from freebitco.

I've thought about all of this a couple of times and wondered if we are really being fooled, but I usually wave the thought aside after some time believing that the winners may not want to make themselves known.
