The sites were, 'dedicated to the advertisement of child pornography, the discussion of matters pertinent to child sexual abuse', according to Ars Technica

The agency's sites also monitored: 'methods and tactics offenders used to abuse children, as well as methods and tactics offenders used to avoid law enforcement detection while perpetuating online child sexual exploitation crimes.'

The FBI hoped to distribute malware to users of the sites so that they could be identified.

Cybercrime expert Fred Jennings told Ars Technica there is: 'no other way to read (the documents) than websites 1-23 were hosted at a government facility, with the FBI's knowledge and to the FBI's informational benefit. 

'It's clever phrasing on their part.'

An FBI spokesman said he was unaware of an operation with 23 websites, according to a statement given to the website.
