She was happy with her job, and as I know, she is still satisfied with the money she gets from it. Usually, it's around $500-1000 and even $2-3k for one day of work. It's happened because we live in a poor country where it's hard to find a job even with a degree, so you need to survive somehow. And we were younger and more naive.
Anyway, the thing is that she was part of the community of webcam models, and most of them working 4-8 hours a day and got around $300-500 in a week. Most of the money goes to 5% of models that appear on the first page.
It's a super competitive job, and your only way is to find regular customers who will visit all your streams to tip and talk about random things. There was an old dude who takes private and talked about his daughter and family issues. He was lonely and just want to speak anonymously to someone.
But there are also real creeps, one of them even somehow found out where we live and our city and travel here (to Eastern Europe from Korea) to report my ex to the police. He demands that she must have sex with him if she wants that to stop. He was nice to her, and everything was fine, but one day she rejects his request (some crazy fetish things), and he goes mad, and all that happened. You're right. The most significant fans are also the ones who go apeshit when something goes wrong for them, and it's scary to think about people like that and what they can do to break someone's life.
