In your Blogger dashboard, head over to Design and then on Template.
Click on Edit HTML.
Search for the
<script src='https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js'/>
<script>$('.comment-content a[rel$=nofollow]').replaceWith(function(){return ($(this).text());});</script>
NOTE: If you already have the part that’s
highlighted in red already in your template’s code then exclude it and
just copy the remainder of the code.
Save your template and you’re done. By pasting the above code in
your template, all the hyperlinked text in a comment will be converted
to simple [unclickable] text.
OR, if you’d rather have the hyperlinked texts removed entirely than just disabling
the hyperlinked text, then copy/paste this...
