  "title": "Public URL shorteners are prohibited in every registration field",
  "statement": "No public URL shortener may appear in the description, message flow, samples, HELP reply, or either confirmation message.",
  "rationale": "Shorteners hide the destination, so carriers cannot assess where a message leads and block them categorically. Tools typically check only the sample messages, but the prohibition covers every field — a shortener in the HELP reply or the opt-in confirmation is rejected exactly the same way.",
