Whole industries cannot advertise. They still need customers.
Not because they are doing anything wrong. Because the ad platforms refuse the category outright, or a regulator restricts what may be said and to whom, or both at once. A licensed dispensary, a bail bondsman, a firearms retailer and a registered investment adviser have nothing in common except that the two channels every other business starts with are closed to them.
So they spend anyway — on channels never built for them, with agencies whose answer to a prohibited category is to do the prohibited thing more carefully. Nobody sells them the thing they actually need, which is a map of where they are still allowed to go.
Ichnos is that map. It learns an industry’s own language, follows it to the rooms where that language is spoken, and then does the part nobody bothers with: it reads each destination’s own words on whether it accepts anything from outside, and quotes the sentence.
Each industry is searched 20 separate ways — trade vocabulary, the rooms it leads to, and seventeen further angles the survey keeps scoring against each other, several of which it wrote for itself after reading what the others kept missing. The angles are not published. How many there are, is.
Survey progress
298 of 408 industries mapped deeply enough to sell · 110 still short
The access mapped so far is worth an estimated $18.4M–$148.4M a year, of which $17.8M–$140.4M can simply be bought.Estimated. We do not hold rate cards for these destinations and do not claim to — the figures are banded from published trade-media norms and each route's own kind of access and authority. They are deliberately conservative, and a buyer who thinks the bands are wrong can substitute their own; the comparison still holds.
An industry reaches publishable depth at 24 confirmed open routes — enough that a buyer has a channel strategy rather than a direction. Below that it is not for sale, and the page says so. This is the survey being built in the open; the figures move several times a day.
The Lockout Index
Which categories are shut out most completely — and which still have the most left. Scored on how severely a category is blocked, whether it carries more than one blocker at once, and how many of the doors we actually opened turned out to be shut.
Most shut out
- 1Horse racing and pari-mutuel96% of 512 doors shutRefused outright by the platforms, and restricted by a regulator on top
- 2Livestock auctions and order buying96% of 513 doors shutRefused outright by the platforms, and restricted by a regulator on top

Scored on three observable things: how severely the category is blocked, whether it carries more than one blocker at once, and the share of places we mapped that publish nothing for outsiders. Industries where fewer than 40 places have actually been read are excluded: ranking those would rank our own coverage rather than their situation.
Find your industry
Three figures, for the one category you care about: how many places we have found where your kind of business is reachable, how many of those have told us in their own words that an outsider may take part, and how many of those you can simply buy.
VPN and privacy tools
Circumvention claims are restricted by platform policy and the tools are unlawful in some jurisdictions, so global campaigns are prohibited somewhere by default.
- Places found
- Publications, associations, forums and directories where your industry’s own language is actually spoken.
- Confirmed open
- These say in their own words that an outsider may take part. We quote the sentence, so you can judge it yourself rather than take ours.
- You can simply buy
- Advertising, sponsored placement or event presence — a budget and a decision, not an application.
Ways in
Start with twelve, free
Twelve places that will still take you — real names, real links, and what each one lets you do, sent to your inbox so you have them to work from. No card, no account. Every industry page already names the routes that cost nothing to pursue, free and with no email at all; this is the same list delivered rather than read.
Or buy the map, or ask for one
Maps are sold per industry at $497, once — $1,997 for categories whose buyers sell capital projects, regulated disposal contracts or bulk commodity positions, where one won contract clears six figures. Each industry page states its own price. Keeping one current — quarterly re-verification of every route in it, plus the log of what opened, closed or changed terms in your category — is $997 a year; every industry at once is $2,997 a year — see what each includes. Every one is a real document — see a sample before you decide: it is the genuine medical tourism map with the first three entries in each section shown in full, quoted policy sentences and all, and the identities after that withheld. If your industry is not on the list, say so — a request moves it up the queue faster than anything else, because it is demand telling us what to build rather than us guessing.
How it works
Three stages. Each is measured separately, so we always know which one is leaking — and the one that is leaking is the one that gets worked on.
Learn the language
The vocabulary an industry uses among itself — its regulators, licences, statutes, trade bodies and technical terms. Say them correctly and you are inside the trade; say them wrong and you are visibly selling something.
Find where it is spoken
The publications, associations, forums and newsletters where that vocabulary actually appears. Not where an audience might plausibly be — where its language demonstrably is.
Check the way in
Whether each destination accepts anything from outside, read from its own advertising or submissions page and quoted verbatim. This is the step that turns a list of places into something you can act on.
The ways in are rarely what people expect. Almost no trade publication says “write for us” — what they publish is an advertising page, a press-release wire, a business directory, an events prospectus, a membership. For an industry that cannot buy ads on the major platforms those are not lesser options. They are the channel, and a site that sells advertising has already decided that outsiders may reach its audience.
Locked Out
Every article about advertising is written for somebody the platforms will take money from. This one is not. A journal about the restrictions themselves — what they say, what happens when businesses try to get around them, and where these industries can still be reached.
Running this for clients?
If you are an agency or consultancy carrying several restricted categories, the question is not whether one industry is locked out — it is how much of your roster you have actually mapped. See the coverage for your categories — free, no email.
What it will not do
A product sold to people who cannot advertise, which itself worked by spamming, would be ridiculous. The restraint is the argument.
- It never posts anythingIt maps and it verifies. What gets sent, and whether anything is sent at all, is always a person’s decision.
- It never calls a route open on its own authorityThe most an automated check can conclude is that a destination publishes a way in. A human decides whether to use it.
- It does not sell contact detailsAnd it never will. A route is a place, not a person — there is no list of anybody here to buy.
- It shows counts, never routesThe destinations are the asset. A preview is a sample somebody can extrapolate from, which is why there isn’t one.
Industries that are lawful, licensed where a licence exists, and restricted by platform policy or advertising regulation — rather than by a record of enforcement for deception.
Every term in that sentence is a fact you can check, which is the point: we do not decide whose lockout was deserved. That is the judgement the platforms already made, and disagreeing with it is the reason this exists.
