Corinna Kopf was already a well-known personality before landing on OnlyFans, the private and paid social network for adults. Kopf, known as Pouty Girl on her official Instagram, earned roughly $100,000 a month, sometimes more, just by uploading her photos to the Facebook-owned app. But a few weeks ago, the streamer, who also generates a lot of income on YouTube, decided to open an OnlyFans and has seen her income multiply considerably.
