Correct. OP, you are expecting  a lot from the staff in my opinion. The staff will act according to the forum rules and not the law. You cannot expect them to go to the house of a scammer and beat them up for cash.

If you have proof of what you claim, take the proper route and then only you can recover your loss. In this case, it does not seem to be worth it for the amount of work you will have to do for that but it is your call finally. I hope you get this resolved.
