It’s not possible to delete your Technorati account. You can try to contact their customer support to have your account removed, but their service isn’t the most responsive (if all).
As one of our users points out, to close a Technorati account one needs to send an e-mail to someone
called ‘juicypeanut’. She needs to have your e-mail address and user name, and you may ask her to also remove your blog from the Technorati directory. However, many users have pointed out that account removal requests are completely ignored.
