Travelling to the USA on a visa waiver (ESTA)?
Homeland Security are now looking to gain access to the last five years of social media activity to check you're not a threat to national security.
Not that I have any intention of ever going to the USA again, but this would stop me in my tracks... and for the US hoping to see an influx of visitors for the football world cup, this may have a chilling effect on any tourism bonus expected.
One more threat to privacy!
