I don't think it's marketing, and I don't think it's the models taking revenge.
Chad has been representing Brent Corrigan since the flap started, and he's seen the real and the fake IDs that were used. Several other models are rumored to also have been shot when they were underage.
The FBI often takes quite some time to take any action... a company I know of, that was involved in insurance fraud, didn't even know they were being investigated for months... then the FBI showed up... then about a year of nothing... and then an indictment.
So I don't think we can assume anything at this point.
