Well, more or less I am in the same situation, like everyone else who is trying to squeeze some money from this faucet. At least for personal piece that I didn't totally waste my time.
I am at 86% withdrawal, and there is no more winnings even with thousands of spins. Obviously they are a scam site.
At the other hand I am wondering how they do it. I did try several things to 'cheat the cheater'- none of them worked. It is not the cookies that give them my ID- I deleted them during play, I modified them, I blocked them... It should be the script that tells the website- if balance>=??? win % =???. I deleted it, deleted all the external http addresses (it works until you refresh the page), and still in a non winning streak. As soon as I log in with low balance wallet- satoshies are coming... I am sure there should be a way to bypass the id recognition- because at the end it is just a way of communication between my browser and their server. I don't have the knowledge to do it- but some of the people here might figure out a way...
