You should be careful of what he told above, he literally asked here if he could open 10 alt-accounts in order to milk the perks more efficiently, and now he's asking about using VPN... IMO the better answer is to ask him why he doesn't just try to use the site fairly like a normal random user instead of looking for ways to make money from it.
You are hugely mistaken, I am not going to abuse their system, these are just fair questions that I want to know, usually you'll see that almost every casino has these questions in their FAQ but since I was unable to find them on Freebitco, I asked this in this thread. You probably don't know but I have a thread in Service Discussion board -
List of VPN Service Providers. The reason why I asked about VPN usage is that majority of people on this forum value privacy and I'm one of them too. So, please be careful with your words.
