freitasm: I haven't seen this anywhere... Sure the emails are different?
Could you please give me a list of #[number] you received?
Hmm, I think they pointed to different posts now that you mention it, but either ways they weren't relevant at all - as in they would always point to a different post in the previous page. And this happens regardless of whether there was a new post or not. Unfortunately I don't have those mails as I've emptied my trash. Will keep a close eye the next time this happens and I'll post in here.
Edit: Speak of the devil.. :)
So I just got another reply alert. Now it's sort of clear what's happening. although I received the mail just now - 2:19PM - the mail is dated: Tue, Mar 13, 2012 at 6:57 PM (3 days ago!) The link in the mail is:

So it appears somehow the reply alert mails have been queued up and the gz server is spewing them at random intervals..
