Nothing here was inferred from the shape of the site and nothing was scraped from a page that did not load. If the policy has changed since it was read, it has changed — go and check, which is the point of quoting it rather than summarising it.
Who this destination is useful to
It appears in the survey under this category, which are industries the major advertising platforms refuse outright or restrict heavily.
Why this exists
Whole industries cannot advertise — not for anything they did, but because the platform refuses the category outright, or a regulator restricts what may be said and to whom. They still need customers, and nobody sells them the thing they need, which is a map of where they are still allowed to go.
So we built the map. This page is one destination out of it, given away because the question it answers is one somebody was already asking. See the survey.
