A US-born NASA scientist was detained at the border until he unlocked his phone
Their point about how other countries will take the US's stance as a cue is somewhat scary.<p>If you try and cross any border it will be relinquishing access to all accounts.<p>I'm assuming email also comes along with 'social media', since communication is by its definition social.<p>So how do you protect yourself? 
I think just going with "Don't have any social media" isn't a good answer because the relationship that children growing up today with the internet is almost completely different to even people 10-15 years older than them.<p>Someone having carte blanche access to a person's phone will find something if they want to.<p>Imagine you're in a few group chats, someone mentions doing some drug. And you've just entered a country where that's an instant prison sentence.<p>Maybe some off colour jokes about politicians? Proof to kick you out or at least detain.<p>I imagine we're at the cusp of something much more unsettling. The technology to reverse image search a face is available today. It's pretty easy to make you appear associated with anything, anyone, etc.
