While I turned down a similar request on Super User, our tooling and circumstances are very different - and in discussions with a Server Fault moderator, the prospect of having additional automatic flags (up to 4) with a human in a loop for the final flag came up.
It might be a good idea,for maybe a month or two (or as the folks directly involved see fit), to help mitigate spam waves with additional assistance this way for posts with a high certainty of being spam - since SF dosen't currently have the same core of regulars, nor the tooling we've set up on SU over the past two years for now.
