This WordPress tip is aimed at those who have not bothered to update their software for sometime. If use or rely on Technorati they will soon stop indexing sites that have not upgraded to the latest software.
Technorati are taking this action due to the number of security breaches that have been detected in recent times. These breaches include the insertion of hidden links on blog pages created prior to the version 2.3.3 update. To quote a lengthy piece from Technorati’s blog post on the topic:
Blogs that have been compromised by this security vulnerability are typified by having links to spam destinations inserted onto the blog page. These link insertions may be invisible to casual observations; the links are often obscured by style attributes that render them invisible.
You can check your blog for links using the page source code or the Tools – Page Info – Links option in Firefox. The ramifications are, again from the Technorati blog:
Because of this ongoing problem, we’re discontinuing processing crawls of blogs that exhibit common symptoms of being compromised. We strongly recommend upgrading your WordPress installation. Even if you haven’t been afflicted by a compromise, by the time you are aware that you have been a number of negative consequences may have already occurred (for instance, flagged spam by Technorati, Google or Yahoo!) — this has been reported by many WordPress users.
The last thing you want is to suddenly lose your rankings within Google or Technorati due to ‘link selling’ when in actual fact you have been spam linked. The biggest WordPress tip for the year so far is to upgrade to the latest software, check your pages for any spam links, and protect your hard earned rankings.
