Cannot find the result of round 10 and 11 or maybe there's no event rolled out for this.
They announced the winner of round 10. You can click

They also sold the tickets for round 11, but they never announced its winner and they never even gave any explanation as to why they didn't do the lottery for round 11.
Well, we cannot say whether or not they did the lambo lottery for round 11, what we know is that they never or have not announced the winner, as a matter of fact, they must have done the lottery and a winner gotten but they forgot to update the lottery winner page for the round 11 contest, and we seeing how the site have been operating for over a year now, I believe this is very possible..
Communication has been completely zero, so let's not make it seem like them not announcing the round 11 lottery winner is the only thing they have not communicated about, alot of things have happened with the site and made some good number of users lose money and not a word from the team behind the site about it, so we should not be surprised that they are yet to announce the winner of the round 11 lottery and yet haven't said anything since then.
