Isn't this a scam? And I am actually wondering who are the users that are going to be buying the tickets for the current lambo draw when the winner for the previous draw hasn't been announced for over five months now.

This are one of the reasons what always make me believe that freebitco is currently operating on auto-pilot, where all features that has been automated to operate on their own are currently running safely without any major issues, the the features or part of casino that needs human actions have been left to suffer, a good example is this which you said, there is no way the system will automatically pick a winner and announce it without human interference, and this is why they have not announced a winner since.
