The entry for the lottery to win the lambo is only 1 ticket. There are plans to start a pool here on this forum to combine all the golden tickets but the requirement to join the pool is 10 tickets.
As I understand it is in case the proposal of equal share is accepted by all. Otherwise I see no reason why not to accept users with lower numbers of tickets (if the prize is shared proportionally).
And yes, the question if subject like that could be discussed in that topic is a separate thing. Another topic needed?
