Apple and Google’s app stores have a child sexual abuse app problem.

While investigating apps that let livestream viewers pay to watch child abuse, The New York Times reports that it found “more than 80 apps that advertised children” on the Apple and Google app stores.

The livestream apps downloaded from Apple and Google illustrate an even darker aspect of the social media technology boom, particularly for children living in poverty in developing countries. There, with the ease of a smartphone, parents and other adults can connect with pedophiles in the United States and elsewhere who pay to watch — and direct — criminal behavior.

Trigger warning: This Times story includes descriptions of child sexual abuse.
