This is pretty much what I suggested in the other thread. For whatever reason, it would appear that certain performers have been singled out for "review" of some sort. Out of all the films that Diabolic has out there, they only looked at performers that appeared in 23 of those videos.
It would be interesting to know who they were looking at, as it might give an ideas of the type of material that the FBI is looking at in this situation.
I personally am betting on performers with either ID that isn't exactly correct, performers using foreign IDs, or performers that appear "younger than average".
The next visit will help to narrow this down.
