Why this rule existsrationale

CTIA's residual harm clause is what catches the damage nobody wrote a category for — a message that names a third party's debt, address or medical appointment to somebody else, or that asserts something ruinous about a named business. The recipient of a privacy leak is not the person harmed by it, which is why no complaint-driven check finds these and why the clause is written as a sweep. Businesses reach it innocently through personalisation: a template that renders the wrong record, or a referral message that tells the recipient why their friend needs the service.

How to fix itremediation

Strip any third-party detail out of the message body and address the recipient about their own relationship with you only. Where personalisation pulls in another person's data — a referrer, a dependent, a co-signer — replace it with a reference the recipient already holds, and remove any assertion about a named business you cannot document.

Common mistakespitfalls

  • A message that is accurate can still fail this: disclosing a true fact about someone who is not the recipient is the violation, not getting it wrong.

Notesnotes

This is CTIA MPBP §5.3.1, which is written as a catch-all covering several harms that have dedicated rules elsewhere. It is kept whole rather than split so the limbs nobody else owns — privacy invasion, safety risk and defamation — are not lost between rules; the criteria route the overlapping limbs so a single defect is reported once.
