I have never heard that anyone won that lambo or opted for the BTC instead. This could have been easily faked or was it a well trusted member from the community that confirmed to have won that lambo? Please don't tell me it was a two days old newbie account letting everyone know they hit the jackpot.
If you are interested, you can search through this thread and find discussions of previous Lambo lottery draws. If I'm not mistaken, there were at least 2 users who told about their winnings in the Lambo lottery, and they weren't newbies on the forum.
Well, that was when freebitcoin was working without any issues. Now, at least the 11th round of the Lambo lottery has not been drawn yet, and it looks like no one is going to do it.
