Delete all Facebook posts for a year

delete_comments_likes.js

// Only tested in Chrome...
// Must browse to "Your Comments" (or "Your Likes") page of activity feed, then pre-load the year you want to delete
// and as many comments as possible (scroll down, they load lazily).
//
// I ACCEPT ABSOLUTELY NO RESPONSIBILITY FOR THIS DOING BAD STUFF. THE NEXT FACEBOOK DEPLOYMENT
// COULD WELL BREAK THIS, OR MAKE IT DO THINGS YOU DO NOT EXPECT. USE IT AS A STARTING POINT ONLY!
//
// It will start failing once it gets to the end, just reload the page and kick it off again.
