I was curious how Adobe was going to monitor/enforce this. In the article:

And again, outside of hitting users with an ever-classic "pretty please," it's unclear how Adobe actually plans to police this kind of material.

Basically, they can't. Maybe if someone was reported, their account can be deleted for violating a TOS. I feel like this is just an adobe CYA in the event someone creates nude photoshoot of a celebrity, so Adobe cannot be held responsible.
