On #WTFWednesday, the privacy threats we tell you about always get a “WTF?” from us because we can’t believe they’re happening. This week, we’re telling you about something we can’t even believe is possible.

Well, the objects mentioned do all have one thing in common: they can all vibrate. There’s your clue.
