Rulez- I'm sorry to hear about this but just put it behind you. The guys talking about a lawyer must be newbies. You can't beat an established cash book in Costa Rica. You aren't beating a new Bitcoin book in CR. Criminally the best thing for the government would be for them to have a wire tap and have their own guy place bets. They don't have it and you aren't getting anything if they were found guilty. You aren't getting anything if you get the real names of all involved. The government isn't going to waste their time on this with so little evidence. Prosecutors have to win a high percentage of their cases to maintain their jobs. If they lose, it's a waste of tax payer dollars. It's a sad story but you have to leave it alone.
I think you are wrong. Things have changed quite a lot and the DoJ is interested to seek out these sites but it does also require a substantial value or volume in terms of $$. Nevertheless it's worth a shot. And there's plenty of evidence from government document fraud (falsifying trademark certificates), email and internet fraud, and defrauding of players, and probable more. I think there's a shitload of evidence.
