Anyone can copy a code list. Publishing a list that still works is a different job. Every code on this site goes through four checks before it is marked active.
We record where a code came from — the developer post, the in-game notice board, or the official social channel — and keep that link attached to the entry.
Codes carry a checked-at timestamp. Anything older than the game's typical redemption window is treated as suspicious and queued for re-verification.
Where possible we confirm a redemption through community reports. When a code fails for several players in a row, it is flagged expired automatically.
Expired codes are not deleted — they are moved to a clearly marked list. That keeps the page useful without wasting your time on dead entries.
