It is a "standard" 100x100 size, at the moment it is very profitable to buy pixels when the cost is 0.000075BTC per pixel so I will leave the customers to do as they please, "faking" bought pixels would be unfair and give the wrong impression to potential buyers and I want to build the website on mutual trust, I want every customer to be certain that I got his back and I am not going to swindle people out of their money.
Why would you have to "fake" it? Can't you sell a few to yourself? Or to get the ball rolling, hold a raffle and give away some for free.
