'' The Verge '' also tested SurfSafe at doing what it was supposed to do and found it came up short . It tested on two widely circulated altered images : one a Seattle Seahawks player apparently burning an American flag as his teammates cheered in the team 's locker room ( the flag had been added to the original image , which had merely showed him dancing ) , and another of Stoneman Douglas High School shooting survivor and gun control activist Emma González tearing up a copy of the U.S. Constitution ( it had actually been some shooting targets ) . While SurfSafe easily recognized the most widely circulated copy of the first image , it did not similarly flag variants , which had also widely circulated on Facebook , that had been cropped or were screenshots of the image taken from elsewhere . It was even less successful with the González image , recognizing no variant , not even screenshots on the Snopes page debunking the image . On his blog , Hacker Factor , Neal Krawetz , an expert in network security and image analysis who operates the FotoForensics.com website , took a very negative view of SurfSafe . Acknowledging that it was a response to a real problem , he warned that it was complex and that " this desire for a fast , simplified solution opens the door for lots of snake-oil solutions and charlatan products . " Krawetz excoriated other publications that had written positively about SurfSafe , suggesting they had only rewritten the press release announcing its release instead of downloading it and reviewing it
