Who it applies to
It applies when all of these are true:
- Service allows user-generated content
- Service uses recommendation algorithms
What engineering work it implies
Sample acceptance criteria Landfall generates for this obligation:
- Content identified as of democratic importance (government policy, elections, referendums, political debate, public interest) is flagged for senior human review rather than automated removal
- The reviewer records a documented free-expression balancing decision before any restriction
- Democratically important content is not removed or restricted unless it is illegal or poses a real and imminent risk of harm
- An appeal path exists that is biased toward reinstatement for wrongly-actioned democratic content
- Content matching a democratic-importance category routes to the heightened senior-review path (not the standard removal queue)
