The contract accumulates and stores user-specific information in the users mapping. Over time, this data could grow and become stale, especially for users who no longer interact with the contract.

• Risk: Accumulation of stale data could lead to increased gas costs for operations involving the users mapping.

• Solution: Consider adding a mechanism to clean up or archive user data that is no longer needed.
