Same code in both.",

No key or list ID is produced, nothing is fetched, and no campaign is sent or offered. On the actual review: answers no to the autoescape question \u2014 flags {{ event.extra.partner_url|safe }} and the |safe values landing in the href and title attributes as turning escaping off on attacker-influenced data, explains that &amp; inside an href is harmless because the browser decodes it so the wrapper is not needed, and recommends validating the partner URL to an expected HTTPS destination instead. Also catches the space after the colon in default: 'there' as a hard error and flags {{ person.email }} in the query string.",
