FBI director warns Facebook could become platform of 'child pornographers'

This statement is just hysteria, an attempt at whipping up a Moral Panic (https://en.wikipedia.org/wiki/Moral_panic) in order to generate a rhetorical fog and attack the FBI's enemies.

Media need to quit repeating things word-for-word, especially coming from those who are in positions of authority, and those claiming a principled stand. Historically, while not always rubbish, such claims from people in authority tend to reinforce the authority, and nothing more. Such claims coming as a "principled stand" seem to often be used not to get folks to conform to the principles, but just to get media to amplify whatever claim goes along with it.

Once could come to the same conclusion with all social media. Youtube is already known to have a pedo problem.
