words on a page
The number of words on a child abuse website page ranges from zero to a
maximum of 36,484 words, with an average word count of 297.9 words per page.
f f “Zero words”would normally refer to a page with images but no text. This occurs
on nearly 500 webpages with confirmed child sexual abuse images.
ff Images are not always labelled in websites as such. For example, a page with
16 images can appear as if it has 16 images, 1 image (displayed as a collage),
or zero images. If it is zero images, the site has used obfuscation techniques to
intentionally conceal its images.

Recommendation: Further research is needed to determine how words are being used on
9 websites hosting child sexual abuse images. Websites containing child abuse material could
be automatically identified using this word data set and a probabilistic algorithm. This data set could
also be queried for new and emerging terms/words used amongst individuals who seek or trade child
sexual abuse content.
Title bars
Title bars, which appear in the browser’s top left corner, are intentionally written
into HTML documents by a website’s author.
Figuref5.5 A webpage's title is found in the browser's top left corner (see circled text).
ff 44.9% of the title bars were seen more than one time, the most popular of which
was observed 96 times
ff 53.9% of the titles were unique (only seen one time)
ff 1.2% of title bars were left blank (there was no title specified)
Some of the unique titles are similar enough, that although they are not an exact
match, would lead one to believe that they are the same page. For example: 18
ff XXX.childonly photos – FREE
ff XXX.childonly.ca photos – FREE
ff X.childonly photos – FREE
Some titles are so unique, that if a duplicate title bar is found, there is a high
probability that the website is being run or was designed by the same individual.

Recommendation: Carefully track the use of unique title bars on websites hosting child
abuse images. Following the movement of these websites will provide a clearer picture of how
content moves on the Internet.
18 These are fictitious title bars created to demonstrate the fact that title bars can be similar.
