St. Clair High School English teacher Brianna Coppage was placed on leave last month after school officials discovered her page on the OnlyFans website, which she said she joined to make extra money on top of her salary as a new schoolteacher. Coppage tendered her resignation and since has gained over 100 new subscribers and has more than doubled her subscription price. Coppage said she earned up to $10,000 a month on her website.
