How not to append the profile URL to the username in comments

I have a bit of a conundrum. In my profile I have added my Google authorship URL so I can set the Atahualpa to automatically add authorship to every piece of content I create.

But that started adding it to my comments as well.

I had a temporary fix for a while (essentially placing my authorship in the Atahualpa settings), but I am now looking to have guest authors on my site and would like to give them the capability to have their authorship featured as well.

Which means that I need to source the URL from their profile, but i need to do it without it showing up in the comments. As it is right now, no matter who posts, my name and my authorship shows up (since I had to hard-code it in the byline window)

How can I prevent all user's names from becoming a link in the comments area only, without rendering Atahualpa un-updateable (I don't want to start messing with the php)
