The National Post reports in its Saturday edition that "I can't do it anymore," was the last message sent by 16-year-old Chase Nasca, who took his own life in February, 2022, after allegedly being exposed to more than 1,000 unsolicited videos featuring violence and suicidal messages on Tiktok, says a lawsuit filed by his family. A National Post editorial says this was just one of the heart-wrenching stories of on-line child exploitation that brought Democratic and Republican lawmakers together last week in a rare display of unity, hauling the chief executive officers of social media companies to Senate committee to account for their actions. In one striking moment, Meta's Mark Zuckerberg apologized to the families who say their children have been harmed, exploited or driven to suicide by social media use. "I'm sorry for everything you have all been through," Mr. Zuckerberg said. Despite that emotional moment, however, the tech CEOs testifying at the Senate hearing mostly deflected criticism of their products. They argued they were already doing enough, or they tried to blame others, as Mr. Zuckerberg did when he said it was up to Apple, not Meta, to ensure age verification for using the Instagram app.
