-- Recreating or cloning a tainted object creates a new untained object which main contain sensitive data. For example, if you have a tainted `user` object, `const userInfo = {name: user.name, ssn: user.ssn}` or `{...user}` will create new objects which are not tainted. `taintObjectReference` only protects against simple mistakes when the object is passed through to a Client Component unchanged.

-A Client Component should never accept objects that carry sensitive data. Ideally, the data fetching functions should not expose data that the current user should not have access to. Sometimes mistakes happen during refactoring. To protect against this mistakes happening down the line we can "taint" the user object in our data API.

-* Deriving new values from tainted values can compromise tainting protection. New values created by uppercasing tainted values, concatenating tainted string values into a larger string, converting tainted values to base64, substringing tainted values, and other similar transformations are not tainted unless you explicity call `taintUniqueValue` on these newly created values.

 * Do not use `taintUniqueValue` to protect low-entropy values such as PIN codes or phone numbers. If any value in a request is controlled by an attacker, they could infer which value is tainted by enumerating all possible values of the secret.
