Quora: hide duplicate questions
Catches questions with identical titles that appear multiple times in the feed and hides the repeat copies.
Code to copy
// Hide repeated/duplicate question cards in the feed
function hideDuplicates() {
const seen = new Set();
document.querySelectorAll('a[class*="q-box"][href*="/"]').forEach(function (link) {
const t = (link.textContent || '').trim();
if (t.length < 12 || t.length > 200) { return; }
if (seen.has(t)) {
let card = link;
for (let i = 0; i < 6 && card.parentElement; i++) {
card = card.parentElement;
if (card.getAttribute('id')) { break; }
}
card.style.setProperty('display', 'none', 'important');
} else {
seen.add(t);
}
});
}
