Warriors for Innocence is an online based organization whose stated goal is "hunting pedophiles where they fester". From their website, Warriorsforinnocence.org (hosted by Blogger.com) targets online pedophile/sexual abuse related journals and then informs the hosts of those journals, such as Livejournal, of content which they claim breaches ToS agreements. They have also taken steps to inform advertisers of those blog sites of the content of some of the blogs, which they claim has led to said advertisers pulling their advertising from the Livejournal site.

In late May, following the events on Livejournal known colloquially as Strikethrough '07, Warriors for Innocence posted claiming responsibility for the deletion of some of the journals, though claiming that many of the legitimate journals that had been deleted were in fact the responsibility of Livejournal's own overzealousness [2].
