About EchoFeed

EchoFeed is an RSS feed cross-poster that rea

Feed fetchers poll RSS and Atom feeds for readers, aggregators and podcast apps. They usually request feeds only, so they are cheap to allow. Watch for fetchers that pull full pages at high rates.

EchoFeed user agent

EchoFeed identifies itself with this user agent string:

  • EchoFeed fetch bot; https://echofeed.app

Anyone can copy a user agent string. Transfon Security also checks where each request comes from, so a request that claims to be a known crawler but comes from the wrong network is treated as a fake, not as the real crawler.

How to block EchoFeed in robots.txt

We have not confirmed whether EchoFeed follows robots.txt. Add a rule, then check your logs to see that it stopped. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.

Block EchoFeed from the whole site

User-agent: EchoFeed
Disallow: /

Block EchoFeed from some folders

User-agent: EchoFeed
Disallow: /private/
Disallow: /search

Allow EchoFeed only on some folders

User-agent: EchoFeed
Allow: /blog/
Disallow: /

Allow EchoFeed and block other crawlers

User-agent: EchoFeed
Allow: /

User-agent: *
Disallow: /

Things to know

  • Each host needs its own file. Rules on www.example.com do not apply to shop.example.com.
  • A crawler obeys only the most specific group that names it. Once you add a User-agent: EchoFeed group, EchoFeed ignores your User-agent: * rules, so repeat any that should still apply.
  • The user agent name is not case sensitive. We take EchoFeed from EchoFeed's user agent; check Robb Knight's own documentation if it publishes a different robots.txt name.
  • Crawlers cache robots.txt, so changes can take up to a day to apply. Disallow stops crawling but does not remove pages already collected or indexed.

Limits of robots.txt

  1. EchoFeed may not follow the rule. robots.txt is a request that nothing enforces, and we have not confirmed that EchoFeed follows it. Check your logs after adding a rule.
  2. The user agent could be fake. robots.txt matches the name a request claims. Anyone can send EchoFeed's user agent, and a scraper using it is not bound by Robb Knight's robots.txt policy. Only checking the source network tells a real EchoFeed from a fake one.

Treat robots.txt as a statement of your policy, and enforce it where requests arrive.

Who should care about EchoFeed

Publishers

EchoFeed fetches pages when your links are shared or syndicated. Keep it allowed so previews and feeds work, but leave it out of page views and ad requests.

Transfon Security for publishers

Media buyers and advertisers

When ads or posts are shared, EchoFeed fetches the landing page. Those hits are not clicks, so keep them out of campaign reports.

Transfon Security for advertisers

E-commerce

Product links shared in chats and feeds are fetched by EchoFeed. Keep it allowed so previews show the right image and price.

SaaS and APIs

Allow EchoFeed on public pages so shared links preview well, and keep it off the app.

Frequently asked questions

What is EchoFeed?

Does EchoFeed respect robots.txt?

We have not confirmed whether EchoFeed follows robots.txt. Add a robots.txt rule, then check your logs to see that it stopped, and block it by user agent if it did not.

How do I block EchoFeed?

Add "User-agent: EchoFeed" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "EchoFeed" at your WAF. In Transfon Security that is one User Agent block rule.

Is robots.txt enough to block EchoFeed?

No. robots.txt is voluntary, so EchoFeed may not follow it, and anyone can send EchoFeed's user agent, so a fake EchoFeed ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.

Should I block EchoFeed?

Feed fetchers poll RSS and Atom feeds for readers, aggregators and podcast apps. They usually request feeds only, so they are cheap to allow. Watch for fetchers that pull full pages at high rates.
