Same thing happened to me. Basically I did that a billion times, then came back to this post and it’d logged me into my AV Club Disqus account. See if that works? Try an incognito window?

(It does really fuckin’ suck.)

Well, I did the “Claim your account” thing and it took me to a Disqus page, then the browser just closed. Am I verified? I fucking hate this already.
