Let me be clear,I only want to use a VPN or TOR for my own privacy and security, I don't want to break any rules by having multiple accounts.
Unless you're using multi accounting to abuse the system, you're probably fine. FreeBitco.in does not prohibit the use of VPN and similar technologies. But keep in mind that using multiple accounts to claim free BTC bonuses or abusing referral bonuses is strictly prohibited and your account will be frozen if you are caught doing this. Most gambling sites, including freebitco.in, employ various methods of detecting users who have set up multiple accounts or otherwise abused their platforms. This is not limited only to the IP address of a user's connection; other details are also tracked.
Quite frankly, Freebitco.in are laid back when it comes to this kind of security and VPN issues. I myself, have not received any issue accessing my account with different VPN. Also, way back when I'm only earning crypto on different faucet sites, freebitco.in was also one of my go-to platforms and honestly, I had multi account on these faucet sites and I also haven't received any issue with withdrawing my faucet earning on this platform (I stopped doing faucet a long time ago). I'm not quite sure if things have change with that but it's better to be cautious than be banned on the platform.
