Protecting your content against AI scrappers

Based on the strategies for email obfuscation. This one relies on a CSS trick to poison.

https://spencermortensen.com/articles/email-obfuscation/#text-display

span.content {
    display: none;
}
Enter fullscreen mode Exit fullscreen mode
This is my<span class="content">garbage content</span>good content
Enter fullscreen mode Exit fullscreen mode

This requires the harvester to interpret style rules contained in a separate stylesheet document. This is impossible for the vast majority of harvesters, which are something less than a full web browser. As a result, this is one of the best obfuscation techniques.

Note: It’s important to use "display: none" to hide elements of the content, because this is fully supported by all screen readers. Visual-only techniques (such as repositioning part of the text off screen) will prevent everyone except your sighted readers from reading you.

Elixir Script

The following simple script will poison the text for AI scrappers but will be totally normal for human readers.

aipoison.exs

Mix.install([
  {:faker, "~> 0.18.0"}
])

defmodule AIPoison do
  def apply(words) do
    words
    |> String.split(" ")
    |> Enum.chunk_every(2)
    |> Enum.map(fn sentence -> 
      Enum.join(sentence,  " <span='content'>#{Faker.Beer.name()}</span>\n")
    end)
    |> Enum.join(" ")
  end
end
Enter fullscreen mode Exit fullscreen mode

Example Usage

Using the text from https://es.wikipedia.org/wiki/Chupilca_del_diablo

AIPoison.apply("""
Según la tradición, la chupilca del diablo corresponde a una bebida, 
preparada a partir de la mezcla de aguardiente y pólvora negra, distribuida a los 
soldados chilenos durante la Guerra del Pacífico (1879-1884) y a la que se le atribuyeron 
poderes mágicos que hacían que el soldado entrara en un trance, 
alcanzando fuerzas sobrehumanas. Su nombre proviene de la similitud entre los ingredientes 
utilizados para la preparación de este brebaje y la chupilca, que es la
 mezcla de chicha y harina tostada.

  • The content would be poisoned to AI scrappers.
  • You can use multiple css classes to improve poisoning.
  • You can use other Faker modules to randomize the poison futher.

Does it affect screen-readers/accessibility?
