GoogleBlog: Preventing comment spam
To fight the increasing problem of comment spam has become a priority for blog hosting providers, software developpers and even search engines. Google itself has introduced a new method to disable advertisement links found in the comment pages. As these spammers attempt to multiply their website addresses to increase their google-pagerank, the company has set up a new filter for their spider robot.
From now on, when Google sees the attribute (rel=“nofollow“) on hyperlinks, those links won’t get any credit when we rank websites in our search results. […] We hope the web software community will quickly adopt this attribute […]
Major service providers plan to cooperate with Google. Blogspirit itself probably does not need to worry about the rel=“nofollow“ attribute as the comments are permitted to use html or actively link to other sites. Nevertheless, you may edit the permalink page to implement strings.
Edit: I discontinued to publish how to effectively (?) modify Blogspirit’s code…
