Very many times I see an email notice about a new registered user. I click on the email link and then Q2A reports: Page not found.
I assume that they are spammers that they delete their profile after they realize that posts are strictly moderated and stand no chance to post anything.
However today I happened to be on my email inbox, I noticed the moment a new notification email came, I immediately clicked on it and again I saw the "Page not found". How can the user have deleted his profile so quickly? Maybe there is some other situation here?
