How we rate the data
Every number on this site carries a confidence level, a date and a trail of independent reports. Here is exactly how that works.
18+ only. Informational; legality varies by jurisdiction.
Confidence = independent sources
Independent means a different platform or a different author. Two posts by the same person on the same forum count as one source, not two.
What “N reports” means
Each observation is one dated report — a forum thread, a catalog listing, a field note. The counter on a city page is how many of them sit in our base for that location.
Freshness
Every figure carries the date of its freshest underlying report; the city page shows the latest one. Reports older than about 18 months are retired from the published picture.
Why ranges, not exact prices
The same service prices differently by district, venue tier, season and format — a single “exact” number would lie. We publish the span from the lowest to the highest verified observation, and a price reaches the page only when at least two observations back it. A lone price never appears alone.
Why dollars, and why rounded
Local prices are converted to US dollars and rounded coarsely (the rate date is on every price page) — enough to compare cities and plan. Exact local-currency ranges, district breakdowns and dates come from the bot.
What we never publish
Raw sources, links, quotes and author names stay in the internal base — they never reach the site. You see the verified result, not a wall of links.
The rating moves with evidence: fresh corroborations raise a figure’s confidence, and observations age out of the published picture over time.
