I wonder if anybody else get multiple copies of replies to subscribed threads on their mailbox?

I've been getting it on my e-mail account. The latest was for a post on "Baguio Represent" ... the same e-mail notification has 16 copies in my mailbox.

It doesn't happen most of the time. And it doesn't happen to mails from the other forums I have subscribed to. Just wondering if it's a quirk with my Hotmail mailbox or with Tsikot.
