Today I remembered that it is impossibleto to comment to this blog. If I remember correctly, this was due to the fact that my host provider told me, I should stop sending thousands of mails a day with this account.
As a matter of fact, thousands of spam bots registerd as a user and Drupal just confirmed their attempts. Still, I have several hundred pages of lists of unapproved users somewhere in the backend.
For my bloody Drupal noob past me the easiest way was to deactivate user registration. Today, present me was challengend by understanding what past me has done... but finally: here you go, and comment - but mind the captcha.
