It's a long shot, but unless you want to go after the scam site owner on your own, it's the only chance to get back the coins.
if they live in the same country as you then you could bring a lawsuit against them i suppose. but lawsuits cost money. unless you are your own lawyer (small claims court?) and even then it would cost you money to file and maybe travel to the defendants jurisdiction. all over 1 bitcoin. and in small claims you can't get more than $5000 or so i heard. so you might have to settle for that. or be eaten alive by some lawyer.
