If anyone has any information on the admin please feel free to PM me. Also don't post that you do in the thread, I can help you with a strategy on getting funds back away from the public eyes in the thread.
Before sending a PM to yonce you might want to check this thread out:
https://bitcointalk.org/index.php?topic=626622.0 Or you could just check his trust, as it is very enlightening. I don't know what his agenda would be but I'm very doubtful that he intends to help out anyone but himself.
If you are on this thread and have emailed or PM'ed the BTC-ARBs person there is a good chance you will be refunded at least your deposit. However, it could take some time.
