It redirects me to the login page, even with incognito. Even the Wayback Machine is getting redirected: https://i.imgur.com/84UDbjG.png

Facebook and Instagram often do this when they don't like your IP (a problem with CG-NAT, VPN, etc).

I tried that, and got a log in page. I also tried to get archive.is to scrape it, and it also got a log in page.

I tried that just now, and got a "you must log in" page.

Interesting, it works for me... Maybe try in a different browser to avoid supercookies / fingerprinting?
