I would love to see the RSOF get an overhaul, and this is one of the features I'd be happy to see.
For those of you that don't seem to understand what a Forum Ignore/Block is, here is a description that will help you.
The Ignore function would enable you to put any forum poster on your Ignore list, much like the in game ignore list. You wouldn't be able to see any forum posts from this user. There could be many reasons for wanting to Ignore someone officially: maybe you find their posts to be overly negative, or maybe you think they are trolls.
The Block function would enable you to block an offensive user from posting on any of your threads. This would be useful if some unkind player was targeting you, specifically. Not only could you ignore them and not see their posts, by Blocking them from posting on your threads, you would prevent them from derailing the thread. (Even if you couldn't see their posts because of the Ignore function, other players could see their flame posts.)
