You will always have people calling reputable sites scam for some random reasons; best is to not pay to much attention to it. Freebitco.in is the oldest faucet that is still running and they are still paying. To the best of my knowledge, I have never seen a legit scam accusation against them.
Even if there was a scam accusation and if it was legit, the owners would have solved it to the best of their abilities. Like any other casino running on this forum for traffic, they know that the crowd here is strong enough in their support and equally devastating enough if they mob up. Of course the second option will never happen that has been shown for the last 10years how legit a site freebitco.in is and continues to do so.
Certain nay-sayers come to the forum often, but lack the proof or evidence that is needed to accuse the casino.
Ofcourse they will because they cannot run a site so successfully themselves. No doubt, freebitco.in has gained massive reputation over the years.
The reason why they are able to sustain for so long is because they value their users and keep everything transparent.
Besides that, when was the last time you heard freebitco.in getting hacked and losing funds ? I never did.
