The New Sudoku Players' Forum

Sometimes I click into somebody's profile page, and see a row written "Please enter 3286: 3286", while mine is "Please enter 3286: 5812".
Then I browsed the Memberlist, and I found that:
For users registered after around 2010, we have 3286, 5812, 3287, 6543, 4321, or 0(or other that I skipped) there, and for ones registered before there isn't that row.
So I guess that the verification code has changed several times.. and I want to know why it is shown in profile viewing page.

Mine says "Please enter 3286: 6543", so I guess I fail that test also!
