Flag to block users from facebook style status?

I have a Facebook style status view that allows anyone to post on anyone's status, not just for friends only.

I want to create a view that block users who have been flagged by current user, but shows all other users.

I created a flag, but it's not working. It only works if I use the field "User: Name" in views, not "Facebook-style Statuses: Poster Name" Is there an argument or something I'm missing? TIA!
