She is credited as the executive producer for the first season, and consulting producer for the second. During the first season, she used her deviantArt page to reply to fans and address questions about the show. She later added a Frequently Asked Questions entry that collected these questions and answers.  
Shortly after the final episode of the first season aired, Faust announced that she had left the show. Her involvement in season two concentrated on story conception and scripts; it diminished through the course of the season. Faust had no involvement in season three though it uses at least one plan of hers that was not used in the first two seasons, and she had no involvement in season four. The My Little Pony Friendship is Magic official guidebook has a foreword by Faust.
