Parents are being urged to fight against apps that allow pornography and human trafficking.
National Center on Sexual Exploitation spokesman Dan Miller tells OneNewsNow that Apple has moved against the social media platform Tumbler, which is popular among people who blog and share content.
Apple dropped Tumblr from its app store.
"And the reason for that," says Miller, "was because child pornography was discovered shared on Tumblr."
Apple could do more to clean its house of more content, Miller insists, such as Instagram, Netflix, and Twitter.
Miller encourages people to visit the National Center website and read about the Dirty Dozen list of companies that promote pornography and trafficking, then contact them to voice disapproval.
More importantly, he adds, parents need to be aware of apps installed on their children's phones and tablets.
