vk_post_mass_delete.js

// 1. Scroll down your profile page as much as you can

// 2. Selecting "Delete" links (for English localization). It will not work on Russian language unless you change this: link.textContent === 'Delete post'
let links = [...document.querySelectorAll('a.ui_actions_menu_item')].filter(link => link.textContent === 'Delete post');

// 3. Removing last N posts if you want to keep them. One comma for each of RECENT posts to be left undeleted.
let [,,,,,,,,,,,,, ...removeLinks] = links;

// 4. Extracting wall.deletePost() calls
let codes = removeLinks.map(element => element.getAttribute('onclick'));

// 5. Calling them each 1000 milliseconds
codes.forEach(code => setTimeout(function() {eval(code)}, 1000));

// 6. Reload page

// 7. Repeat for any remaining posts
