Open your LinkedIn profile, find See all activity, click on posts, open developer tools with F12, find console, paste the code above and press enter.

This is minified code for the bookmarklet. Create new bookmark and copy this code to URL, then click on it on profile > see all activity > posts page

javascript:(()=>{let speedMs=500;setInterval(()=>{let dropdown=document.querySelector('.feed-shared-update-v2__control-menu .artdeco-dropdown button');dropdown.click();setTimeout(()=>{let optionDel=dropdown.parentElement.parentElement.parentElement.querySelector('.option-delete .tap-target');if(optionDel===null){setTimeout(()=>{window.scrollTo(0,document.body.scrollHeight)},speedMs*4)}else{optionDel.click();setTimeout(()=>{document.querySelector('.artdeco-modal .feed-shared-decision-modal__confirm-button').click()},speedMs)}},speedMs)},speedMs)})();

Works like a charm, thanks ! Could you add a refresh function or a click on the "Show more results" button after X iterations ?

2023 updated version

(() => {
  let speedMs = 500

  setInterval(() => {
    let dropdown = document.querySelector('.feed-shared-update-v2__control-menu .artdeco-dropdown button')

    dropdown.click()

    setTimeout(() => {
      let optionDel = dropdown.parentElement.parentElement.parentElement.querySelector('.option-delete .tap-target')
      
      if (optionDel === null) {
        // setTimeout(() => { window.scrollTo(0,document.body.scrollHeight) }, speedMs * 4)
      } else {
        optionDel.click()
  
        setTimeout(() => {
          document.querySelector('.artdeco-modal .feed-components-shared-decision-modal__confirm-button').click()
        }, speedMs)
      }
    }, speedMs)
  }, speedMs)
})()

Having to click the delete button each time for the post to remove. One click is much better then the alternative. Thank you
