It would be nice for FBTC to state not being affiliated with this site (if that is the case), many people are saying that the creators of FBTC are the same ones behind this site, so if (most likely when) bnbfree is found to be a scam, it may, and most likely will, hurt FBTC reputation.
As 'FinneysTrueVision' has said above, the BNB related site is just clone of Freebitco. Most probably they want to target those people who will use their Freebitco account email and same password on that website. It will redirect to Freebitco.in terms page if you click on the terms of that website. The website is displaying the logo of the Curacao Gaming license, while it isn’t verifiable. BNBfree is indeed a phishing website.
