Facebook messed up its "Year in Review" slideshow programming in 2014. A number of photosets didn't only use images that dredged up painful memories, they also ended with "It's been a great year" regardless of their content. It looks like the social network has taken great care not to repeat the same gaffe, though, since 2015's version can automatically block out certain pictures. According to Techcrunch, it uses the same filters as Facebook's Timehop clone On This Day. A spokesperson said: "We won't show you photos where memorialized accounts or exes are tagged, or photos with people you've blocked or added to your On This Day preferences."
