With the Wordpress integration all external comment links get the nofollow attribute.
Is there an option for a do follow for your own domain?
All links besides my own site → no follow.
Thanks 
/admin/settings – search for “follow”
exclude rel nofollow domains
A list of domains where nofollow should not be added to links. example.com will automatically allow sub.example.com as well. As a minimum, you should add the domain of this site to help web crawlers find all content. If other parts of your website are at other domains, add those too.
