Edit your template HTML with widgets expanded and replace:Basically, just remove the part that says rel='nofollow'.
<a expr:href='data:comment.authorUrl' rel='nofollow'>
I did a search (CTRL+F) for comment.authorUrl, deleted the nofollow attribute, and saved my template.
While looking for the directions, I noticed that some people have stopped making their blogs Do Follow because it encouraged spam. I'm probably asking for it here, but I haven't had a huge problem with spam. Sure, it happens every once in a while, and I did have one commenter who repeatedly left spammy comments on one post. I had never used comment moderation until then, but now I have it set so that comments on any posts older than 30 days have to be moderated. So far that seems to be a decent compromise.
Any comments? Have you made your blogs Do Follow? Does it seem to encourage spam, and if so, how do you handle it?
