...Si'.... once in awhile, they sneak in under the radar for a few hours ..
The membership could help the staff out in this regard.
Note the 'red and white' triangle icon, right beside the reputation/scales icon. Clicking that will allow you to 'report a bad post' to the staff. That sends an instant notification to the entire staff, so the next time any of them log in, they are notified immediately and can take appropriate measure.
Saves us the chance of missing it..
