I just installed and ran inactive user. I knew I had some users that had not logged in to the site for a couple of years. I considered them inactive and dead. However, I was expecting the system to send a warning to the users before deleting them as I had setup in the system. Apparently that did not happen because when the first cron was run, my administrator account got plenty of mails telling me about blocked and deleted users.

The module should be aware whether it has sent a warning to blocked and deleted users, if that setting has been activated, before deleting and blocking.
