[...] These workers then shared at least 15 images—including shots of a minor and of a woman sitting on the toilet—to social media groups where they gathered to talk shop.
To be fair, when the photo of a woman taking a shit was shared on facebook, her face was blurred.
Once something is online there's also the (less important but perhaps more likely) risk they'll send software updates that remove features, add adverts, force you to set up an account, and other nonsense like that.
