that proves you have access to the site, not that you are the owner.

On that line of questioning I have a few to add

* do you own the rights to all the games, images and code used to make this site?

* What issues have there been with this site?

* can we see records of profits and losses for the lifetime of this website?

* what things need to be fixed? What are the long term goals for development?

* is the site made with any framework?

* Would the hosting need to change? If not, what are the costs involved?

* any other information about it's value, it's customers, any other services that are included in this ( twitter? ) or anything else that would contribute to this auction.

* Why does your profile have a poor rating?

* why are users warning that you're a scammer and your site steals their coins?
