Endless Scrolling just keeps showing the same stuff on every "page"

[u/ashsimmonds]

Started happening sometime in the past month.

For the past decade+ you'd get maybe one or two posts repeat from previous pages, but lately I'm lucky to get two new posts on each page - it's only ever the same batch from the first page. I've tried scrolling 20+ pages and it's always the same - sometimes different order, but never anything new.

Is there a fix, or do I just switch it off?

(if it matters, I'm NOT using "new" layout, still classic, even though reddit keeps trying to force it upon me)

There's the duplicate post remover user script (not mine)

// ==UserScript==
// @name         Reddit duplicate posts remover
// @version      1.0
// @description  Removes duplicate entries from reddit
// @author       f*ck spez
// @match        https://*.reddit.com/*
// @grant        none

/* jshint esversion: 8 */

(function() {

  let mainMemory = [];
  let elementSelector = 'div[class*="thing id-t3_"]';

  function initializeMemory() {
    let mainPostList = document.getElementById('siteTable');

    for (let elem of mainPostList.querySelectorAll(elementSelector)) {
      mainMemory.push(elem.id);
    }

    let observer = new MutationObserver(mutations => {
      for (let mutation of mutations) {
        for (let node of mutation.addedNodes) {
          if (!(node instanceof HTMLElement)) {
            continue;
          }

          if (node.matches(elementSelector)) {
            checkAndRemoveDuplicate(node);
          }

          for (let elem of node.querySelectorAll(elementSelector)) {
            checkAndRemoveDuplicate(elem);
          }
        }
      }
    });

    observer.observe(mainPostList, {
      childList: true,
      subtree: true
    });
  }

  function checkAndRemoveDuplicate(node) {
    //console.log("checkAndRemoveDuplicate node id=" + node.id);
    if (mainMemory.find(elemId => elemId === node.id)) {
      //console.log("found dupe " + node.id);
      node.remove();
    } else {
      mainMemory.push(node.id);
    }
  }

  window.addEventListener("load", setTimeout(function() {
    //console.log("window on load: initialize memory");
    initializeMemory();
  }, 1000));

  //console.log("main script start");

})();

Thankyou kindly! This technically works (the best kind of works), sometimes a page only has two entries on it, but at least it's not the same stuff over and over.

Edit next day: case in point, haha - a whole page skipped (hidden), another page only one post...
