Delete Facebook Posts by year

delete.js

/**
 * HOW TO
 * Replace XXXXXX by your username in the following url
 * https://www.facebook.com/XXXXXX/allactivity?entry_point=privacy_settings&privacy_source=activity_log&log_filter=cluster_11&category_key=statuscluster
 * Scroll down to a year.
 * Important: you must scroll and see all the posts you want to delete before executing.
 * The script will not auto scroll, will not auto load the posts.
 *
 * Set the year in the configuration.
 * Copy the whole thing.
 * Paste in the Dev Tools console.
 *
 * NOTICE: the code relies on Facebook's markup. The classnames or structure could chance any time.
 * The code might not work but it is not dangerous either. Run safely.
