Mute Twitter accounts sending promotions

twitter-automute.js

// This is neither elegant nor robust, 
// but it _does_ mute everyone sending 
// promoted tweets to my timeline.

// It works by installing a debounced 
// scroll listener which checks for promoted tweets
// and mutes their sender by clicking the resp. 
// tweet context menu action.

function debounce(func, wait = 100) {
  let timeout;
  return function (...args) {
    clearTimeout(timeout);
    timeout = setTimeout(() => {
      func.apply(this, args);
    }, wait);
  };
}

mutePromoters = () => {
  xPathEvaluator('//span[text()="Promoted"]/../../../..//div[@data-testid="caret"]')
    .forEach(promotedTweetMenuActivator => {
      promotedTweetMenuActivator.click();
      setTimeout(() => {
        let muteButton = xPathEvaluator('//*[@role="menuitem"]//span[starts-with(text(),"Mute")]')[0];
        console.log(muteButton.innerText);
