True, but I don't think the creepshot situation is comparable. In the porn case, you have material produced with the consent of the participants (ideally). Those arguing against it are using a speculative argument that some viewers might be led to predatory behavior from it.
In the creepshots case, the material is produced without the consent of the subjects, and is arguably obtained by people who are engaging in predatory behavior and rewarding them for that behavior. The link between creepshots and predators is thus not speculative, and it is combined with a gross violation of the privacy of the subjects of the photos.
Furthermore, the acceptance of creepshots harms all of us in the United States. A key aspect of our Constitutional protections against unreasonable intrusion in our private affairs by the government is the notion of a reasonable expectation of privacy.
When we, as a society, decide that some particular loss of privacy is acceptable that moves the bar a little on what the government is allowed to do.
See this fantastic article by Alex Kozinski, Chief Judge of the 9th Circuit Court of Appeals on how we are giving up our privacy voluntarily and how that is giving more power to the government: http://www.stanfordlawreview.org/online/privacy-paradox/dead...
