Not deleting the Blogs?

Hi. The web site I work on (Progressiveu.org) has installed the user_cancellation module. This module is not deleting the entries as expected when a user cancels his or her account. Instead, it re-attributes the author information to "Guest" as before. We need it to actually delete blog entries if possible.

We offer people a blog on societal and political issues, and explain to them that whatever they write on our space belongs to them. So we needed an easier way to delete the blogs of former users more easily than going in one by one and deleting them - which is what led me to this module. Or, if this is something that can't be fixed, then we need a way to keep the author's name in tact even after the user deletes his or her account.

Thank you.
