I understand why there is reluctance to add the "Ignore Poster" feature although I'd personally be willing to risk it. How about an "Ignore Topic (or Thread)" feature instead? I would find it useful when (unfortunately not if) a topic has been hijacked or has deviated significantly from its original intent. I've already implemented this manually. There are lots of threads I just don't even open anymore. But it would be wonderful if I didn't have to see them in the list.
