Comment (by imath):

 hi,

 When the user is not a group member, he can comment activity or reply to
 activity comment that "belongs" to the group. I think it can be confusing
 for group admins to see that non members can contribute to the group
 content (in this case activity). I wonder if it's a good idea to include a
 "groups_is_user_member()" check on your patch.. and add something to check
 for the membership in case the non member wants to reply to a comment.
 (made a gist to suits my need : https://gist.github.com/imath/4966936)

 So in the same spirit, Boone, i think you should also filter
 'bp_activity_can_comment_reply' to check for banned user, because i've
 noticed on my case that if a member of a group commented on a group
 activity, then a non member can reply to this comment.
