Anti Feed-Scraper Message Plugin For WordPress [Updated November 09]


Anti-feed-scraper plugin is a really simple plugin which helps you give the so-called “feed scraper bots” a hard time.

A feed scraper is a script that explores various XML feeds and bluntly copies content in various categories. The purpose, I assume, is to create a useless ghost-blog with faux contents, either because the bot-puppeteer was lazy or in shady attempts to collect Google juice.

Anti-feed-scraper makes your posts somewhat harder to scrape, by appending a little message to the end of all your posts. Because this message appears in the body text of your posts (only in the RSS feeds of course), it’s hard to filter out by the scrape bots. Which means if the lazy puppeteers keep stealing your content, they’ll steal it complete with links to your original content as well.

The plugin features an options page where you can configure your post message.


In the options page, you can customize the message appended to your feeds. The default is:

[postname] originally appeared on [sitename] on [postdate].

Available “magic tags” include:

  • [postname]
  • [sitename]
  • [postdate]
  • [tweetthis]

    Thanks. This is pretty useful to me.

      What are you considering using it for, if I may ask so bluntly?

        Am I mistaken, or is this an evil evil site that must be shut down?

    2. Joen says:

      That came out slightly wrong.

      I did not mean to imply your content isn’t scrapeworthy. What I meant to say was that “pretty useful” sounds like you intend to use it for something other than “anti scraping”?

    1. Hmmm, doesn’t seem to work for me though. It should show up in:

      As far as I can see I don’t have any other plugins messing around with the rss (and the feedburner link I use instead of the one above shouldn’t matter) just a few which go through the content as it’s displayed on the site itself.

    2. Joen says:

      Actually, it looks like it’s working just fine for you.

      Remember, there’s both an excerpt and a body text in your feed (description and content:encoded respectively). The excerpt, since it’s cropped anyway, doesn’t get the message. The content encoded does. The excerpt is what you see when you view the feed in Firefox. But when you “view source” of the feed, you’ll see this:

      Vertically centring in css (without hacks and multi-line enabled) originally appeared on Candy by James on 18:07.

    3. Ha! You’re right, my apologies, I missed it going through the code.

      Seems Feedburner was playing up, think it’s the Great Google change-over.

    4. Joen says:

      Perhaps you were looking at a cached version in Feedburner.

    5. That, of course, is a very good possibility, and now I feel even sillier for bothering you with it.

    I’m currently considering letting other sites (libraries and such) use our content on their sites (under a Creative Commons license). The automatic link back in the feed saves me a lot of work. 😉

    And yes, the site is going CC by-sa in a short while – just need the “go ahead” from two of the contributors (and if they don’t give that, we go ahead anyway, just without their contributions). All the major contributors have given permission.

    Of course, this will make working together with ComicWiki even easier, with the two sites sharing license and all.

      That sounds sweet. Free forever!

    2. Ulf says:

      Damn straight! 🙂

    Works great, thank you

    Found this plugin in my rummagings:

    apparently it inserts a digital fingerprint into all your posts, so you can detect scraped content. Call that an alternative to this.

    Forgive me for my thick skull, but where is the Options page so I can edit the message displayed? I’ve looked, can’t find it.

    1. Cowgirl says:

      Sorry….it’s in settings, I see it now.
