There is a scam accusation against freebitco.in which you can check here FreeBitcoin Scam?. I know they already have a couple of negative tags; if no one responds to the scam accusation, they will probably get a couple more negative tags. The user already provided proof of deposit to freebitco.in the account, which wasn't credited, and he did not get any help so far. Since this thread already has so much information, I will use this thread as a reference for a Negative tag. It is sad how an old platform ended up being a careless scam.
