I created this thread and watched it: https://xenforo.com/community/threa...members-severe-seo-damage-proof-inside.82495/

There were 2 replies but I didn't got the alert.

Tricky situation, but unavoidable really.

There was a post made that you would have been alerted about. A number of hours later (and after another post had been made), that user deleted the post. Any other posts wouldn't give you an alert because the thread was already unread.
