US Energy Secretary Rick Perry -- who oversees the country’s nuclear arsenal -- has fallen for an Instagram hoax. He reposted a message claiming there was a “new Instagram rule” that would allow the social media site to “use your photos,” according to images of the since-deleted post on Perry’s account. “Instagram DOES NOT HAVE MY PERMISSION TO SHARE PHOTOS OR MESSAGES,” according to the post, which billed itself as offering protection against the new rule if it was displayed on a user’s account. There was just one problem: there was no new rule. “There’s no truth to this post,” BuzzFeed News quoted a spokesperson for Instagram’s parent company Facebook as saying. Perry came in for heavy criticism on social media, with various users wondering whether someone who couldn’t identify an internet hoax should be in charge of nuclear arms.
