I removed Disqus from my website due to privacy concerns. Disqus can be used as logged-in with services like Facebook, Google as all your activity in the web. Through Disqus they can see what people are talking about and make other surveillance actions. At the same time Disqus leaves a lot doubtful cookies with unclear origin.
The best idea do not use disqus at all if you don’t want to share your privacy with other 3rd parties like Google.
You can always contant me with email.
