It may comes as a surprise, but WordPress has its own commenting system on the same server, instead of Jetpack, Disqus, or any other comment plugins. And Disqus, to no one’s surprise, almost always wins the nomination for best comment platform.
Since the new version of Disqus and WP, it had failed to notify me to moderate new incoming comments. Sorry folks, if you had any questions that needed my immediate attention, I simply didn’t get the message. As of now, (like 2 mins ago) Disqus is disabled. Also, I do wish to point out that I’m not planning to enable it anytime soon. Apparently there had been an outcry on what Disqus is doing to “moderate” the comments of a community. updated Dec 3, 2017: retitled from “Disqus Is Temporarily Disabled on MTP”.
