Over the years facebook collects lots of data about their users. But a lot of this data, e.g. picture, video, comment, visited place and liked posts are lost in timelines. FacebookProfileStalker is a tool that shows all public information for a given facebook profile. It doesn't involve any hack or hacking, it just displays public info from Facebook's official graph search. Please be aware that results depend on privacy settings: if information is set to 'friends only' it will only show up for Facebook friends. The website itself is ment for a personal privacy checkup, not for stalking.
