Guhn, 47, whose real name is Clinton Raymond McCowen, was scheduled to go on trial July 1 on charges of obscenity, racketeering and money laundering, and faced up to 90 years in prison. By pleading guilty to the money-laundering charges, he avoids trial and faces three to five years in state prison.
Craft, 40, and Stevens, 38, each pleaded guilty to one count of racketeering and face two to four years in state prison. Dwyer, 41, pleaded guilty to wholesale promotion of obscene materials.
The men left the courtroom without comment and will remain free until their sentencing hearings, which are set for Aug. 11.
McCowen owned Ray Guhn Productions. Stevens was a producer and website technician for the company. Craft was responsible for recruiting models, finding locations for shoots, making the movies and paying the models.
McCowen also owns and operates CashTitans.com, an affiliate program
Guhn's defense, led by adult-industry attorney Lawrence Walters, had planned to introduce publicly accessible Google search data to try to convince jurors of Pensacola residents' interest in sex-related material.
Assistant State Attorney Russ Edgar, who was prosecuting the case, called the pleadings a major victory.
"We have this problem statewide," he told The Pensacola News Journal. "I hope prosecutors will take our lead and enforce our law."
