Make user invisible

This is not the same :)

With you add-on, this gets used to all members, which posts are moderated. Not usable for me.

Why ?

1. The number of moderated posts gets higher and higher, because there is no special place for this specials members.
2. In our forums all users get moderated a number of posts, when they register. They would also not see the message.
3. When a users gets "harveyed" from us, we don´t want to approve one of his posts, but they still will be in the moderator bar for approving.
4. The more users you "harvey", the more posts you got in moderation and on and on.
