What is this

Disqus decided to introduce some bs affiliate links (via https://disq.us/url → https://redirect.viglink.com). uBlock blocks this, so you won’t ever get to where you want to go.

If you log in with a Disqus account, you may also be turn it off.

When you’re at the “Page Not Found” screen, just click on this bookmarklet to continue to the actual link target.

Use it

javascript:location.replace(location.search.substring(1).split("&").reduce((prev, curr) => {let x=curr.split("="); prev[x[0]]=decodeURIComponent(x[1]); return prev;}, {}).u)

Drag this code to your bookmarks toolbar and give it an appropriate name.
