In a previous discussion here on HN, there were several folks who claimed that they were (or should have been) affected that did not receive an notification from Disqus but did receive a notification from HIBP.
According to their statement[0], they have 17.5 million emails to get out. Unless they routinely send several times that volume daily, they'll have to batch the notifications over the next few days or the entire thing will get blackholed.
> We are currently in process of emailing all of the impacted users directly. Getting all 17.5 million emails out will take us a few days, but we wanted to get this disclosure post out as soon as possible. Additionally we've posted links to this disclosure in our publisher admin panel, user homepages, and on disqus.com.
