Stephanus, you would had lost your best bet. I have couple sub-accounts but I am active only on two of them. Probably this will not be enough for you but I will try. Currensee.com scans all Oanda's sub-accounts so you can go there and watch my profile (my name is Grzegorz Gruszka). You will see that only two accounts there are active. Currensee’s GRGQW.D is “bumbum”, GRGQW.G is “MA-six”.
Focus on your own trading my friend instead of looking for scammers.
