I tried removing the Disqus comments on this post: https://blog.intercom.io/the-dribbblisation-of-design/ and Printliminator will not remove them. I'm quite sure I've removed them before, but it did not work in this case.
I think the main issue is that the Disqus comments are inside an iframe. And since it is cross domain, it might not be possible (I haven't tested it yet) to interact with the contents of that iframe.
