Even if she goes to prison for a short sentence, she will still make a living from it when she is released.
I find it really sad how short-sighted these people are with regards to throwing away theirs and their families dignity and respect, as well as the prospect of any decent future employment, for the sake of a quick buck. She might be making a reasonable wage now, but the work won't last. As the industry becomes more and more saturated with people willing to degrade thememselves for cash, the rates they can get away with charging will fall rapidly.
If she'd worked as a prison officer and climbed the ladder to management level, she could've had a guaranteed decent enough wage for the rest of her life. Her family and friends would've respected her.
I can't help but feel sorry for people who do Only Fans and that kind of "work". I cannot imagine having so little respect for myself, and those I love.
