If people would open their eyes and read instead of just believing a headline they would find out that the site that is originating all of this discussion is using an almost one year old article from the L.A. Times that does not identify any of the individuals that tested positive.
And if people would delve further into the story, instead of believing only the headline, they would discover that the people who tested positive were people who had never made porn movies but they were new people trying to get into the biz and were summarily rejected because of their positive status.
The headline on that site was made only for the sole purpose of driving traffic to the site.
