Maybe I posted this discussion on wrong place because I am a newbie?
No, this is the right section for scam accusations, but for one thing I think you're probably being a bit premature in making one, as people have pointed out that freebitco.in is a reputable faucet/gambling site and second, when you're making an accusation against someone or against a service you need to follow the scam accusation format, which is stickied on the first page of the section. That would include providing evidence that you got scammed--and that's probably the most important part, because if you don't then nobody is going to take your accusation seriously.
Hope you get your issue resolved, because that's not a trivial sum of bitcoin. If you do, why don't you follow up here and tell us what happened.
If you want to know, I can tell you personally.
As you could see, many people are just trying to blame me because I am new here,
and Freebitcoin must not be a scam because they have a good history.
