Unlike facebook, LinkedIn creates entire posts just for likes and comments which fills up the feed with crap. This snippet removes posts from the feed that aren't proper content.

LinkedIn - Remove crap posts.js

const removeCrap = () => {
  const $crapSelector = $(`
    span.ember-view span:contains(" likes this"), 
    span.ember-view span:contains(" commented on this"), 
    span.ember-view span:contains(" liked "), 
    span.ember-view span:contains("Short course you may like"), 
    div.feed-shared-text-view span:contains("Promoted")
  `);
    
  const crapCount = $crapSelector.length;
  
  if(crapCount === 0){
    return;
  }
  
  $crapSelector
  .closest('.relative.ember-view')
  .remove();
  //.css('opacity','0.3'); // Fade out instead of remove
  
  console.log(`Removed ${crapCount} LinkedIn BS posts.`);
};

setInterval(removeCrap, 100);
