A new user has registered -> Page not found

Question

Hello

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?

What is the link that comes through on the email? Is it the correct format for your site?

Yes, it is the correct format.  When I click it it takes me to the q2a site.  The problem is that the user does not exist any more.
