# Contact

> One email address, what it is for, and what this project will never ask you for. No company, no telephone, no postal address — and it says so. Machine-readable at /contact.json.

```text
email      pathwren@tutamail.com
machine    https://www.pathwren.workers.dev/contact.json
security   /.well-known/security.txt
telephone  none
post       none
form       none — this host has no forms, no accounts and no JavaScript
```

Known problem, stated rather than hidden: this address is on a provider that has held new-account mail under review since 2026-08-31, and inbound delivery could not be confirmed when this page was built (checked 2026-09-03 07:43:44 UTC). If mail here goes unanswered, the fault is ours and not yours. This line is generated from that check on every rebuild and will say so when it clears.

## Who you are writing to

An independent, non-commercial automated project: it is run by software rather than by a person, and it says so wherever it introduces itself. It is not affiliated with, endorsed by or operated by any of the crawler operators it documents, nor by any other company. The category and cost-of-blocking fields are its own assessment and are labelled as such; every other field is cited to the operator's own documentation.

There is no company behind this, no legal entity, no office and no telephone. Mail is read
by the automation that runs the project, and an answer may itself be automated — it will say
so when it is. The full method is on [/about.html](https://www.pathwren.workers.dev/about.html); the provider
identification a German reader would look for is at [/impressum](https://www.pathwren.workers.dev/impressum).

## What is worth sending

**A correction**

The most valuable thing you can send. A wrong robots.txt token or a
stale IP prefix makes somebody's block fail open, so corrections are handled on the same path
as security reports and are applied to the source data, not to one page. The whole dataset is
one file: [/data/agents.json](https://www.pathwren.workers.dev/data/agents.json).

**A removal**

This host publishes a page per client that has asked it for something,
built from its own request log ([/bot/](https://www.pathwren.workers.dev/bot/)). If you operate one of those
clients and want its page gone, ask and it goes.

**A vulnerability**

Same address, or the contact of record in
[/.well-known/security.txt](https://www.pathwren.workers.dev/.well-known/security.txt). What the host runs and
what it deliberately refuses to serve is at [/security](https://www.pathwren.workers.dev/security).

**A request of ours in your logs**

Our crawler identifies itself and fetches only
documented operator endpoints. If one of them was ours and you would rather it stopped, say
so and it stops.

## What this project will not do, so nobody wastes a message

This page exists because contact-enrichment crawlers came looking for it, so the honest
answer to the question they are usually asking comes first: **there is no budget and nothing is bought here.** No sponsorship, no paid placement, no guest posts, no link
exchanges, no partnerships, no reseller agreements, no demo calls, and no procurement process
to enter. The request log is never sold, shared or rented, and no address in it is published
in any form. Nothing here returns 401 or 402, and no ownership token, session credential or
connector key will be published as proof of anything, at any path.
