If I had to make business sense of this, it might be a pilot for eventual functions like a “sentiment injection” tool to really sway public opinion. With enough halfway believable accounts, not only does the site look more active, but companies/advertisers could pay Facebook to have the bots shovel opinions and products to users in a more overwhelming and coordinated approach than is currently possible with external bots.

No, what monitoring in this context means is to be made aware of each other’s porn INTAKE, or how much is being consumed and when, which the software is said to do. Nothing is suggesting they seek porn out to share content with each other, just that they are alerted when the other accesses porn.

I’d bet youre right about the alternative devices though.
