User A is the account with smallest user number that can still be opened.

he Joined MM YYYY Where the MM is the exact month and YYYY is the year.

The first User Number account after 10000 that joined the same MM YYYY and can still be opened is User B

User B's Score also is the User Number of User C

User Delta is user with a Double Digit Master Number for User Number

The user is 25 years old.

Their last ranked game on that account was XX months ago

XX XX XX is the user Number of another user. Which has XX 3 times next to each other. His name has LLLL amount of characters in his name.

We Multiply the score of User C by LLLL and combine with the user number of my account which leads us to User Gama

The Question is . . . .

What does User Gama's name mean in Japanese.

HUNT : I complain about those people all the time . . .

Edit 1 : Fixed the hint for User B . Now it properly shows where to be searched for.

Edit 2 : Fixed the User Delta explanation to make more sense.
