This is a feature of the Feast Plugin
Remove the link from the author name in the comments.
This is an extension of the remove website field from comments form feature, which just prevents new comments from containing an author link.
To deal with existing author links in your comments, you either need to delete them from the database, or simply hide them from displaying.
Why remove it
The author link in the comments is:
- A source of broken links (bad user experience)
- Unrelated to the post content
- A source of spam
- Unnecessary external links, diluting internal link equity
Additionally, even legitimate, useful comments that link back to your food blogging peers are nofollow'd, which means they provide no useful benefit for the comment author.
