delete your tweets and un-retweet tweets

in-your-console.js

// go to https://twitter.com/your-username, and enter the following into the developer console:
for(var i = 1; i < 500; i++){ // just do it a bunch
  // Un retweet
  document.getElementsByClassName("ProfileTweet-actionButtonUndo")[i].click();
  document.getElementsByClassName("js-close")[0].click();
  // Delete tweets
  document.getElementsByClassName("js-actionDelete")[i].childNodes[1].click();
  document.getElementsByClassName("delete-action")[0].click()
}

I have used this script and it has been working for a while, do you have any of yours working for it?

^ modified the previous code to also "undo retweets"

(function () {
  var delTweets = function () {
    var tweetsRemaining = document.querySelectorAll('[role="heading"]+div')[1]
      .textContent;
    console.log("Remaining: ", tweetsRemaining);
    window.scrollBy(0, 10000);
    document
      .querySelectorAll('[aria-label="More"]')
      .forEach(function (v, _, _) {
        v.click();
        document.querySelectorAll("span").forEach(function (v2, i2, a2) {
          if (v2.textContent === "Delete") {
            v2.click();
            document
              .querySelectorAll('[data-testid="confirmationSheetConfirm"]')
              .forEach(function (v3, i3, a3) {
                v3.click();
              });
          } else {
            document.body.click();
          }
        });
      });
    document
      .querySelectorAll('[data-testid="unretweet"]')
      .forEach(function (v, _, _) {
        v.click();
        document
          .querySelectorAll('[data-testid="unretweetConfirm"]')
          .forEach(function (v2, _, _) {
            v2.click();
          });
      });
    setTimeout(delTweets, 0);
  };

  delTweets();
})();

you may need to refresh the page and restart the script every so often since it seems twitter rate limits loading tweets

now longer work for likes
