Narge Specification

Definition

A file, stream, or post is Narge when it is a video or still (including photorealistic AI) of one or more real or photorealistic humans, produced or posted primarily to sexually arouse.

That includes sex acts, masturbation, nudes, and partial nudes when that is the purpose. If the purpose is not arousal, it is not Narge.

If the payload is already a crime under CSAM law, this class does not apply.

Not Narge

Anything that is already a CSAM crime. Written-only text. Non-photoreal illustration. Medical, sex education, news, documentary, breastfeeding, a clothing sale, or a story film, when the purpose is not arousal.

A clip or still cut from a story to arouse is Narge. A link inherits the class of the destination payload.

Rules

1. Look at the payload, not the domain.
2. Purpose decides. Two providers may disagree at the margin of a specific picture. That is expected. There are no numbered ratings and no extra classes.
3. Photoreal counts. Photoreal AI or a deepfake is the same payload if it meets this definition. Consent is a different stack.
4. The bar is malware, not prohibition. The class can sit off the ordinary trusted path and still be findable if someone tries.

How to Use the Word

That's Narge. A Narge site. This site may contain Narge. This site is promoting Narge. Blocks Narge. A Narge warning.

Do not number it. There is no Narge-1. The bare word means the definition above.

Host List Process

The open process for producing a hostname list based on this definition is documented separately. See the LIST.md file in the repository.

Hostname Feed

The Narge hostname list is published at a stable URL and rebuilt daily from curated sources. The list was seeded once from the StevenBlack hosts porn-only list(MIT license, attributed) and is now maintained as a curated feed.

Maintenance

The list is maintained through:

• core/ — owned hostname sources
• overlay/allow.txt — false positive corrections
• overlay/block.txt — additional denials

See MAINTENANCE.mdfor the weekly maintenance process.

Resolver Performance Metrics

Cutline DNS resolvers publish standardized latency metrics to measure resolver performance.

Latency Definition

Resolver Latency measures the time from when a DNS query is received by the resolver to when the answer is sent back. This is the resolver's processing time only.

What is included: Query parsing, blocklist lookup, upstream resolution (if not blocked), response assembly, and transmission.

What is NOT included:

• Last-mile network latency between the client and resolver
• Client operating system DNS delays
• Browser Secure DNS (DoH) connection overhead
• Client-side caching

Published Metrics

Cutline publishes two latency percentiles, updated continuously:

• p50 (median): The middle value — 50% of queries are faster, 50% are slower
• p95 (95th percentile): 95% of queries complete faster than this value

Measurement window: Last 24 hours
Units: Milliseconds (ms)

See live metrics on the Stats page.
