I think, I would be more than happy to post the code on how the winner is selected. And some documentation about the code, however I would be hesitant of releasing all of the code in case somebody created a rip off of the site. But we all trust our local game shows / lotteries in our normal currency, and also draws in our own currency, so why shouldn't it be trusted in a crypto currency. As I previously said I am here purely to provide some fun and a members of the public a chance to win, hence why would I want to cheat the system? The cost of the lottery itself is covered by the 5%, that is good enough for me.
