by default you do not have to approve
bbpress will hold for moderation items that Akismet deems to be spam, that wordpress has for moderation in dashboard>settings>discussion>before a comment appears and comment moderation
You might also have additional plugins that are causing moderation
Thanks Robin, sorry if I confused there, I could only find a plugin which allowed you to moderate all items.
But was looking for a plugin which allows you to set certain keywords to flag to administrators/moderators, and/or hold those posts/comments as pending review.
I do believe now that this is part of bbPress out of the box, is that correct?
bbpress uses wordpress moderation settings in
dashboard>settings>discussion>comment moderation
Set keywords up in there, and bbpress will moderate using them
