There is no user named "Gimmick?", only a user named "Gimmick". It is possible to log into "Gimmick?"s account by typing in "Gimmick" or "gimmick", though, so you probably just typoed while registering.
Yes, hiding your IP address also hides your location. It's important to note that anonymity is a trade-off. You don't let people know who you are, but at the same time you make it a lot harder to prove to people like me that you are who you say you are.
Can you give me the time you registered? What day it was (or at least what month)? Time of day (and timezone) would help, too.
