To the Editor:

“Child Sex Abusers Elude Flimsy Digital Safeguards” (“Exploited” series, front page, Nov. 10) should be a wake-up call for the tech industry. It is no longer acceptable to hide behind “privacy laws” when the health, well-being and future of so many children and young people are at stake.

Now is the time for tech companies to put the safety of children first and own up to their responsibility in ending sexual exploitation and the abuse of children online. They must use their position and resources to invest in the technological solutions that identify and promptly take down abusive material, as well as work with national and international law enforcement to put in place robust reporting processes and legal accountability.

No child should be exposed to the perpetual cycle of abuse and trauma that the article describes.
