Ask HN: Way to delete fb and minimize leftover info

Hey guys, I haven't logged in to facebook in about a year now, and it's been over 4 years since I used it in any meaningful capacity. I'm sure that facebook will maintain some kind of shadow profile of me, since it's aware of my existence, and will do so even after I quit the platform, but I figure that there are technical barriers to maintaining these shadow accounts (I imagine that they don't store the entire edited comment history of all posts etc) So I was wondering what types of steps should I take before I delete facebook. Is there a convenient way to overwrite all my posts and remove all my likes etc? Any way to overwrite the photos I've uploaded (only about 6 or 7), and delink myself from all the photos I've been tagged in etc (assume it's automatic after account deletion) Sorry I don't have a clearer query, I haven't used it in so long that I don't even know everything I want to have removed about me, but I'm trying to delete myself as best as possible. Thanks in advance!
