  "statement": "A scope-clarification question may appear in the opt-out confirmation only where the consumer consented to several distinct message categories.",
  "rationale": "Asking \"which messages would you like to stop?\" of somebody who receives one kind reads as an obstacle, and the FCC treats a revocation as complete unless the consumer chose to narrow it — so the question buys nothing and delays the suppression. Where a consumer genuinely consented to two or three categories it is legitimate and useful, which is why the rule is about the mismatch rather than about the question.",

  "remediation": "Where the campaign sends one category of message, make the opt-out confirmation unconditional and final. Keep a scope question only where the consent covered separately-described categories, and treat no reply to it as a full revocation. Done when the confirmation matches the number of things the consumer agreed to.",
  "example": "Single-category campaign: \"Acme Coffee: you have been unsubscribed and will receive no further messages. Reply HELP for help.\"",
  "pitfalls": [
    "A scope question that keeps sending until the consumer answers it inverts the rule — silence is revocation of everything, not permission to continue."
