Okay, so the draw is visible over there but you can't really identify what your tickets are. You can indeed see your total tickets and what tickets you own yourself (even though not all of them, right?) but you can't see what tickets others own. I don't think this really ensures anything. Do you disagree?
You can check every single one of the tickets you own, and if you really want to bother, you can check everyone else's tickets as well.
Little example:

So, anything else?
