Without actually registering I assume this is a web-based game. Meaning everything is handled server side (assuming the creators of the game ain't retards).
If it's the above case it's not possible without actually hacking access to the web database keeping all the info about every player in the game.
Or if your able to do some SQL injection, again this again requires that the host is an complete idiot.
Assuming the that who ever made this game wasn't stupid, I'd tell you to give up. But then again if you pay 500~1000 USD some hardcore hacker might consider actually hacking access to the database. Good luck.
