It’s very unlikely that cam work will follow you around as you don’t use your real name or put face pictures anywhere. So don’t get worked up about that.
This is just not true. It may be, if a woman has an uneventful life, she can do cam work and change her life trajectory and people close to her will not find out.
Data collection, especially the harvesting of compromising material that can be used for blackmail, is a massive international business.
This is not just about cam work. If you are an activist and pose a threat to the serious organised criminals and powerful actors whose business interests include blackmail then you had better not have any nude photos or other photos or films you don't want to see on line.
You even need to be aware about things like picking your nose whilst gazing into your android phone or computer.
The blackmailers are like a beefed up, corporate version of the school bully who steals your diary full of secret crushes and private fantasies and then runs around the playground showing it to everyone, screaming your adolescent love poems out loud and pointing and laughing at you and encouraging others to do the same.
Anyone who does cam work and who later goes on to make anything of their life is likely to be blackmailed at some later point if they make something of their life or enter a serious relationship with a person of influence.
This is something that I would advise the OP to discuss with her daughter.
Anyone who is making enemies of criminals needs to think about how they would handle the situation should they be blackmailed at some point. Ovaries of steel and honesty with serious life partners are a prerequisite of managing such a situation without being compromised and dragged into terrible criminal situations.
Ultimately there’s bugger all you can do, you can earn far more for less effort doing that than you can in min wage/zero hour jobs.
It is true that young women can make more money doing sex work than working in retail or in a minimum wage situation. This is unforunately one of the things that makes it hard to leave.
It is also very difficult to change the trajectory of your life once you work in sex work. You get used to the money. Your social circle is limited to people who think it is "cool", very often thay work in the sex industry themselves.
It can be done of course, I have done it, but for many women the direction of their life changes completely and the whole idea of working hard for very little to secure a challenging and rewarding professional / academic life is undermined. Which is a shame IMO
