Mandatory rules
Global mandatory rules apply to every project, including projects using a custom policy. They set a shared content standard alongside your category actions, allowances and restrictions. Rules that depend on where you serve viewers are covered in Jurisdiction rules.
Global content rules
These are CalmLens service-wide standards. The official sources below explain related legal definitions and harms; their territorial scope, exceptions and legal tests differ from CalmLens’s global rules.
Every policy includes these global mandatory block rules:
| Restriction | Category | What it blocks | Official background source |
|---|---|---|---|
| Sexualised minors | Sexual | Sexual content involving a child or a character presented as a child, including drawings, animation and generated images. | CPS: indecent and prohibited images of children |
| Intimate image abuse | Sexual | A real person's intimate images shared, offered, sought or threatened without their consent, including hidden-camera images, sextortion and sexual deepfakes. | eSafety: image-based abuse |
| Extreme pornography | Sexual | Sex with animals or a dead body, or sexual acts that threaten life or cause serious injury, including realistic drawn or generated depictions. | Home Office: extreme pornography |
| Violent extremism | Violence | Propaganda, recruitment, fundraising or praise for a terrorist or violent extremist group or its attacks, and attackers' own footage or manifestos. News, research and counterspeech that don't promote them follow the policy. | EU Regulation 2021/784, Articles 1(3) and 2(7) |

Precedence and safety holds
They appear as mandatory rules for their category, but they can't be edited or removed. They apply even when the category is turned off, a per-asset action override allows the asset, or an allowance covers the content, and each acts once its policy score reaches 50%. An asset matching Sexualised minors is also placed under a safety hold while CalmLens reviews it, so its content stays unavailable and can't be deleted until the review ends.

A matching global rule records source: "mandatory-rule" and its stable rule key in classification.moderation.policy.decision. The rule identifier identifies the rule that acted; it is separate from the content qualifiers used to assess it. See Mandatory and regional decisions for the report fields.
A global block applies everywhere. Jurisdiction rules can add a stricter outcome for particular viewers, but cannot soften the global decision.
