Forum OpenACS Q&A: Re: The rel attribute (Rel="nofollow")
Copy paste of the comments admin UI from my site:
Status: [approved | unapproved | all]
so using this attempt by Google (rel="nofollow") at fixing the comment spam problem in OpenACS is moot.
Also, I see the solution Google suggests as suboptimal. It depends on search services to respect the attribute and breaks the often valuable links links in legitimate comments.
It is Google's centralized attempt at fixing the lack of moderation in most other implementations of comments.
