// Idea:
// This script hides all the popular posts. I figured that most of the popular stuff
// that I must know about are already on the news like HN or WSJ or TV etc.

// maximum number of reactions that a post can have and not get flagged as a viral jargon
const MAX_REACTIONS_THRESHOLD = 150; // arbitary number that works for me

// mode = 0 => remove posts
// mode = 1 => just make the background red for flagged posts
// It is advised to run this script with mode = 1 for a week or so,
// to observe the number and type of posts getting flagged
const mode = 0;


const redColor = 'rgba(255, 0, 0, 0.75)';

const removePopularPosts = () => {
  document.querySelectorAll('.relative.ember-view').forEach(feedElem => {
    const reactionsElem = feedElem.querySelector('[class*=reactions-count]');
    if (reactionsElem && reactionsElem.textContent) {
      try {
        const count = parseInt(reactionsElem.textContent.replace(/,/g, ''), 10);
        if (count > MAX_REACTIONS_THRESHOLD) {
          if (mode === 0) {
            feedElem.style.backgroundColor = redColor;
            feedElem.style.display = 'none';
          } else {
            feedElem.style.backgroundColor = redColor;

// Run once
