In 2021...

We assessed a webpage every one-and-a-half minutes.

Every two minutes, that webpage showed a child being sexually abused.

People report to us at iwf.org.uk, or through one of the 49 Reporting Portals around the world, in multiple languages. All reports are assessed at our headquarters in the UK. We also actively search the internet for child sexual abuse imagery. We call this, ‘proactive searching’.

  • 361,062 reports were assessed by IWF (20% increase from 2020):
    • 360,834 were reports of webpages and
    • 228 were reports of newsgroups.
  • 252,194 URLs (webpages) were confirmed as containing child sexual abuse imagery having links to the imagery or advertising it (64% increase from 2020).
  • Additionally, 5 newsgroup reports were confirmed as containing child sexual abuse imagery.
  • No reports were confirmed as UK-hosted non-photographic child sexual abuse imagery.

Note: Each year, a number of these are adverts or links to child sexual abuse material.
