How to bulk comment Disqus and Facebook?

Anyone knows how to make comments into blogs who has enabled the Facebook and Disqus?

There are some software or method out there?

I cant find anythink relatad to that, since you need to be logged into Disqus or Facebook to comment.

Google indexes that comments too, we can make a lot of auto approved comments that way and improve branding.

Also its a good way to build nofollow links.
