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.
