Instructions for blocking wherever.audio

This page is for publishers wishing to block wherever.audio from accessing their content.

Assumptions

wherever.audio assumes that if a publisher posts an RSS feed with publicly accessible links to their audio files and images, then the publisher wants this content to be available in podcast player software. This is how podcasting and all podcast players work.

That said, some publishers may not want their content appearing in specific applications or platforms.

Acknowledging this, we offer instructions below for how to block content from appearing in wherever.audio.

Access types

wherever.audio accesses published content in the following ways:

  1. Direct requests for RSS feeds, images, and audio files
  2. Proxied requests for RSS feeds
  3. Search result listings that display show title, description, and image.
  4. Suggestions section that display show and episode titles, desriptions, and images.

The rest of this document describes methods for blocking each type of access.

How to block direct requests for RSS feeds, images, and audio files

wherever.audio is an HTML and javascript application that gets delivered statically and runs in the end user’s browser.

As a result, with narrow exceptions covered below, there is no middleman between the user and the publisher’s content server:

  -----------------                                -----------------
  |               |    RSS feeds, images, audio    |               |
  | javascript in |     ---------------------->    | publisher     |
  | users's Web   |     <----------------------    | server        |
  | browser       |                                |               |
  |               |                                -----------------
  -----------------

Referer-based blocking

Like all Web applications, wherever.audio sends a Referer header with every request. For wherever.audio the Referer looks like this:

Referer: https://wherever.audio/

Blocking this Referer string will block access by wherever.audio.

Feed-based blocking

wherever.audio respects the podcast:block tag. It will block access if the id wherever.audio is present, like this:

<podcast:block id="wherever.audio">yes</podcast:block>

Proxied requests for RSS feeds

wherever.audio accesses publisher feeds via Cross-Origin Resource Sharing (CORS) requests.

In order for CORS requests to succeed, publishers must set specific HTTP headers that enable Web-sharing. Many publishers fail to do this, more due to oversight than intent in our experience.

How can publishers overlook these headers and still grow an audience? Most podcast apps run in iOS and Android, where they can sidestep CORS enforcement. In doing so, they gain a significant advantage over pure Web-based applications.

In order to create a level playing field and good user experience, wherever.audio falls back to a proxy system when CORS requests fail:

  -----------------                      -----------------                      -----------------
  |               |          RSS         |               |          RSS         |               |
  | javascript in |     ------------>    |   proxy       |     ------------>    | publisher     |
  | users's Web   |     <------------    |   server      |     <------------    | server        |
  | browser       |                      |               |                      |               |
  |               |                      -----------------                      -----------------
  -----------------

Publishers whose true intent is to block Web-sharing, can block access using any of the methods that block direct requests covered in the previous section.

The proxy also sets a User-Agent header which can be used for blocking. Its value is

User-Agent: Wherever-Corsica/x.y.z

where x, y, and z are numbers indicating the software version.

How to block search result listings

wherever.audio’s search is powered by The Podcast Index, which is imported weekly.

  -----------------                      -----------------                      -----------------
  |               |    search results    |               |        weekly        |               |
  | javascript in |     ------------>    |   search      |        ingest        | podcastindex  |
  | users's Web   |     <------------    |   server      |     <------------    | export        |
  | browser       |                      |               |                      |               |
  |               |                      -----------------                      -----------------
  -----------------

To block feeds from showing up in search result listings, we recommend blocking them from the Index. More information on Index blocklisting can be found at this GitHub page.

How to block Quick Picks

wherever.audio’s Quick Picks section offers composite feeds made up of episodes from different shows. To block content from appearing in this section, block User-Agents matching

User-Agent: Wherever-Marquee/x.y.z

where x, y, and z are numbers indicating the software version.

Or add the following tag

<podcast:block id="marquee.wherever.audio">yes</podcast:block>

How to block Auto Chapters

where.audio generates chapter summaries for popular podcasts. These appear on the playback page below the show art during playback.

These may be blocked by supplying your own chapter summaries using the podcast.chapters tag, which is always favored when present.

Auto Chapters may also be suppressed by blocking User-Agents matching

User-Agent: Wherever-Scribe/x.y.z

where x, y, and z are numbers indicating the software version.
