Nomad, websites that use Disqus have to assign their own moderators—not employees of Disqus—and each website owner/comment moderator sets the Disqus parameters for commenting. I’m a moderator on a few sites that use the Disqus plug-in for comments. It’s not Disqus that censors. It’s whoever runs the website you’re commenting on, so in the case you mentioned, it was a comment moderator at Breitbart who deleted the comments.
Well that`s another clue in this puzzle because if I were a tin foil hatter, I`d swear that after his death, the establishment took them over. In my opinion, the place has changed, gone down hill.
