A couple months ago,
Technorati announced that users of
Wordpress needed to upgrade to the latest available version (now at Version 2.5). This week, Technorati announced that blogs remaining vulnerable to identified
security exploits may no longer be indexed by their service.
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.
