This is the supposed Modus Operandi of the admins (or maybe only EY) - making such comments hard to find without deleting them. It has been mentioned here and there and I am fairly sure I experienced a version of this recently when the latest comment in the Open Thread feature on the sidebar stopped showing the latest comment for the duration of this (it could've been a coincidence and it is a decent way to lessen the Streisand effect so I don't blame EY for it)
