It only takes a simple research and anyone wanting to gamble on freebitco.in would realize that that decision isn't a wise one, but unfortunately, people don't search before they register and even deposit to a casino, they only begin to search after they must have been scammed or an issues arose and they can't reach the casino management for help, they begin to search to see if there was other means of contacting the team behind the casino aside their incline customer support system and sending emails.
I think the reason they get too many visitors is their website's domain name. I remember that I found their name on Google because I searched the keyword free bitcoin faucet or something similar. If you search for such keywords, their website will appear at the top, and you will end up signing up at this casino as a newbie. Most people used their platform to claim the hourly faucet back then.
People will probably still search for the same keyword and then sign up for this platform. People don't know about the on-going issues. I wish people would do their research before they start using a website - epecially when money is involved.
