This is a method I have been using for quite a while and I have found that when done correctly it has a 100% chance of working!
What you do is the following:
1 Wait until the person has logged of and log on
2 Open a ticket and have a sort of joke conversation with the gm try to make them laugh and just be normal *Jokingly question them on stupid things, gain their trust*
3 After chatting for a bit ask if are allowed to know their name
4 They will tell you that you can not find it out because it is against their policy or something
5 Then ask if they know yours, they'll say yes and you simply say prove it.
6 Wash rinse repeat with different variations and different gms eventually you will have enough information to fully scam the account
7 ?????
8 Profit
Feel free to flame I actually like it ^.^
