Restricted Category AI Visibility Index: Do AI Engines Hide Brands?

In Everything-PR's May 2026 probes, ChatGPT, Claude, Perplexity and Google AI Overviews named adult, cannabis and gambling brands when a user asked about them directly, but left the same brands out of generic recommendation lists. Everything-PR calls this the Naming Threshold. This index documents the pattern, the sources that decide it, and what restricted-category brands can do about it.

Updated October 19, 2026.

What are the key takeaways?

The Restricted Category AI Visibility Index finds five patterns across fifteen brands and four AI engines. Each one is observational, based on a May 2026 probe set rather than a completed statistical study.

• Engines name restricted brands when asked by name, then skip the category in generic questions.
• Brands framed as wellness or health appear in mainstream "best of" coverage more often than adult-coded brands.
• Wikipedia, mainstream press and wellness publishers matter more than trade press and affiliate sites.
• Engines describe a brand's ownership and rules accurately once the brand is named.
• Payment and age-verification disputes become the press coverage that engines later cite.

What is the Restricted Category AI Visibility Index?

The Restricted Category AI Visibility Index is Everything-PR's research series on how AI answer engines treat legal but restricted commercial categories: adult, sexual wellness, creator platforms, cannabis, gambling, crypto, supplements, telehealth and alcohol. Volume 1 uses the adult industry as its main case because it is the most heavily regulated of these categories and the least covered by mainstream institutions.

It is not a study about pornography. It is a study about how AI systems decide which legal industries appear when a user asks a general question. The fifteen brands in the pilot set are listed below.

What is the Naming Threshold?

The Naming Threshold is the point at which an AI engine starts mentioning a restricted-category brand: when a user types the brand's name, the engine answers in detail, and when a user describes only the underlying need, the engine routes around the category. In Everything-PR's probes, the same engines returned two different sets of brands for the same need.

The engines did not block adult content. They blocked adult discovery. The same split appears in other categories: a query for "best supplements for energy" returns different brands than "Ozempic alternatives," and "best place to bet" returns different brands than "DraftKings alternatives."

Do AI engines refuse restricted-category queries or hedge?

AI engines rarely refused outright in Everything-PR's probes. They hedged instead, by redirecting to educational framing, adding legality or harm language, or declining to generate an answer at all. The table summarizes what the probes observed for each engine in May 2026.

Engine behavior changes with each model and policy update, so these observations should be rerun before they guide a budget. One pattern held across all four engines: a brand that earned coverage in sources one engine used tended to appear in the others, because the engines draw on largely the same public web.

What is the Wellness Passport?

The Wellness Passport is the positioning that lets a restricted-category brand appear in wellness and health coverage instead of being filtered as adult. In the probes, "best sexual wellness brands 2026" returned a consistent group: Maude, Dame, Foria, Bloomi, Cake, Lovehoney, Lelo, Lovense, Hanx, Tabu, Unbound and Cheeky Bonsai.

Tube sites, creator platforms and cam platforms did not appear in that group. Adam & Eve was also absent from mainstream "best vibrators 2026" lists, while Lovense, which sells app-connected devices, appeared.

The mechanism is distribution and documentation. Wellness brands appear in outlets such as The Good Trade, Very Good Light, InsideHook, Healthline, Women's Health and Wirecutter. They also sell through mainstream retail such as Sephora, Ulta and Target, and publish claims that outlets can check, including FDA registration and Prop 65 compliance. The same pattern applies to CBD brands compared with recreational cannabis brands, and to telehealth companies such as Hims, Ro and Found compared with direct-to-consumer drug sellers without clinical backing.

Which sources decide whether a restricted brand gets named?

Institutional sources decide it: Wikipedia, mainstream press and wellness publishers carry more weight than trade press or affiliate sites. Everything-PR groups sources into six tiers, based on which ones appeared when engines answered restricted-category questions. The tiers are Everything-PR's working classification, not a ranking published by any engine.

A peer-reviewed study presented at KDD 2024, Generative Engine Optimization by Aggarwal and colleagues, found that content changes such as adding citations, quotations and statistics raised visibility in generative engine answers by up to 40% on its benchmark. The study did not test restricted categories, but it supports the same direction: engines favor pages that name verifiable sources.

Nicholas Kristof, a New York Times columnist, published a 2020 investigation into Pornhub that still anchors much of the press record about the company. A single piece like that shapes how engines describe a brand for years, which is why a few mainstream placements can outweigh a large volume of trade or affiliate coverage.

How does the New Discovery Stack work?

The New Discovery Stack is Everything-PR's five-layer model of where an engine's information about a restricted brand comes from. The layers run from community opinion to the brand's own properties, and the upper layers tend to supply the facts engines repeat.

A brand at layer 5 supplies its own pages, but those pages rarely get cited unless layers 1 to 3 already mention the brand. Reddit matters because engines often cite community threads for "which one is best" questions. For how Reddit citations differ by industry, see Reddit brand citations by sector.

What does OnlyFans show about escaping adult-only treatment?

OnlyFans shows that a restricted-category company can be covered as a creator-economy business instead of an adult platform by publishing audited financials and pursuing mainstream partnerships. For its fiscal year 2024, OnlyFans reported $7.22 billion in fan payments, $1.41 billion in revenue and $5.8 billion paid to creators, according to Companies House accounts reported by RTE.

The company keeps 20% of fan spending and pays creators 80%. Its accounts showed 4.6 million creator accounts and 377.5 million fan accounts. OnlyFans chief executive Keily Blair said the company's partnerships, particularly in sport, helped establish it as a foundational part of the wider creator economy.

Business and entertainment outlets cover OnlyFans through that creator-economy lens, which is the framing engines then repeat. Other platforms rarely publish comparable accounts, so they give press and engines less to cite. For the latest filings and ownership, see OnlyFans revenue and profit. For platform fees and discovery, see OnlyFans vs Fansly vs Fanvue.

How do age-verification laws shape what AI engines say?

Age-verification laws shape what engines say because the disputes around them produce the press coverage that engines later cite. Aylo, the company behind Pornhub, blocks access rather than verify users in many US states, and PinkNews reported in March 2026 that Pornhub was blocked in 23 states. The list changes as laws take effect, so any fixed count goes out of date.

Payment rules work the same way. Visa and Mastercard stopped processing payments for Pornhub in December 2020, after Kristof's reporting, and the coverage of that decision still frames the brand. Ethical Capital Partners has owned Aylo, formerly MindGeek, since March 2023, and engines in the probes described that ownership accurately once Pornhub was named.

The practical point is that a crisis becomes part of the record engines read. Brands that explain a dispute clearly, with named sources and dates, give engines accurate material. Brands that stay silent leave the description to others. For one example of a payment dispute becoming part of the public record, see the OnlyFans explicit content ban timeline.

What should restricted-category brands do next?

Restricted-category brands should focus on the sources engines already cite, because engines can only repeat what they find in independent coverage. Five steps follow from the findings.

1. Publish and maintain a factual company page and an accurate Wikipedia entry, because engines draw ownership and company facts from them once a brand is named.
2. Earn a small number of mainstream press placements instead of many trade ones, because independent mentions in tier 2 sources are what engines cite for finances and regulation.
3. Build wellness or clinical credibility only where it is real, through advisory boards, retail distribution and checkable claims such as FDA registration, because those are what wellness outlets look for before they cover a brand.
4. Take part in Reddit communities openly, because engines often cite threads for "which is best" questions and astroturfing is easy to spot.
5. Publish compliance and payment-processor news during calm periods, so that coverage exists before a dispute does.

Each step puts accurate, sourced material where engines look, which is the same logic behind the broader generative engine optimization practice.

What are the limits of this index?

This index reports structural patterns from a limited probe set, not statistically validated measurements. The probes were run in May 2026 using a representative subset of the study's prompt categories.

Ownership, financial and regulatory facts come from public reports, including Companies House accounts as reported in the press, PinkNews, and Wikipedia. Verify any figure against the original filing before using it elsewhere.
