Child writing


Stop child abusers in their tracks and prevent the distribution of child sexual abuse imagery hidden by obscure words and phrases with our pioneering Keyword List.

Offenders often create their own special language or code for concealing criminal child sexual abuse material online. Our Keyword List compiles these words, phrases, and codes and makes them available to IWF Members allowing you to stop this type of criminal content on your network or application.

It’s particularly helpful for moderation purposes in chat, gaming, and forum environments and is available solely through membership with us.  

We work meticulously to ensure any terminology is quality assured and we increase the number of terms on the list through ongoing partnerships with law enforcement and the tech/internet industry.

Why choose the IWF Keywords List?

  • Protect children: Every time you block or stop someone from accessing child sexual abuse content on your service, you stop a survivor from being victimised once again.
  • Updated monthly: We update it every month. Our analysts add new keywords as they see them while they work to remove online child sexual abuse images and videos.
  • Quality assurance: All terms and phrases on our Keywords List have been checked by our analyst to make sure they return criminal content. 
  • Unique: The IWF Keywords List includes cryptic terms like letters and numbers associated with child sexual abuse content that other keyword lists wouldn’t recognise.
  • Actively searching: We're one of the only hotlines in the world actively seeking criminal images and videos, so we’re finding more content than anyone else. We’re always looking for new ways to find content using new technology to further develop our expertise and impact.
