I'm only a few pages into this thread so far. I thought of an episode of This Is Life with Lisa Ling that I saw a couple of years ago about Sugarbabies and Sugardaddies. I found it on YouTube.
For anyone who hasn't heard of Taylor B. Jones from
https://thesugardaddyformula.com/ you might want to check her out. If you google her name you can find her on Facebook, Instagram, Twitter, Youtube, etc. She and her Sugardaddy are interviewed in this episode. Their story starts at 17:20.
Most of this episode is interviews with people from SeekingArrangement, including the Founder and people who are members of the site.
