We can have them, no problem. It's just that the "duplicate posting" filter apparently is broken right now. The filter for first-time posters seems to be broken again as well, because the poster you mean is a new forum user as of today, yet his posts got published immediately.
It's great to have some of the former functionality back. That's the way it should stay. But the anti-spam features must be fixed so that they work properly.
PS: The Active Users overview still has not returned.
