Same thing happened with Traci Lords when it was discovered she was underage while doing porn.
What Traci did was a shrewd, brilliant move. As an X-Rated actress (even with a convincing fake ID) she was only paid one time for her movies. She earned nothing from residual sales. By the time she was 18, she was a huge star in the business but made no money from her work. What to do? Easy! She exposed the fact that she was underage rendering all of her previous films and photos illegal and unmarketable. Once her films had been pulled from the shelves, she capitalized on her fame to make one film as a legal adult. Per her contract she retained all control over this film and made a fortune thanks in part to her newfound notoriety. Then she quit the X-Rated business and found modest success in mainstream entertainment.
