Update: I saw this post the internet;
There's a youtube channel with regular content of them from 2017 where it's revealed that she was born in aug 2003 and fernanda looked mid 20s so either an older sister or actually her mother. It's not unheard of for a family member in brazil to encourage a child to do online sex work so it's likely what this situation was in camilas early childhod and why her content took this turn in adulthood.
