I love this idea, but it also needs to be discussed within the context of knowing that (since Snowden) the NSA already has all your social media data categorized and ready to go should it need.

So, in context, this is about stopping one branch of government - CBP - from being able to compile data that another branch of government already has.

I love the idea but worry it might be a form of security theater, given the three lettered elephant in the room.
