Though tbf "underage people sharing nudes with each other on snapchat and looking at porn" doesn't necessarily mean you have to kill the children immediately, you can give them some time.
Besides, it's "you have three months to create and implement code that tracks the ages of all your users and all activity across all apps for the ones under 18, and then use that to stop their cameras from working when nudity detected, and stop their messaging services when nudity detected, and stop their internet when pornography detected." I don't think we need the follow up "lethal force engaged" just yet, but you never know they may start blowing up computers like Mossad's pagers when a kid googles "boobies" soon enough.
