I think you're over exaggerating, some of her clips were fairly popular years ago, but it's been a hot minute. Plenty of girls do what she did, she's not all that special (as much I still love some of those videos).
Ok...? That doesn't mean she's ashamed. If nothing else, there's plenty of legal hurdles that videos with an ex introduces as most sites require continued/changing verification of both parties. She'd eventually have to hide them unless she tracked down the old boyfriend to verify himself and say they were consensual, etc.
It's not surprising they were set to 'private'. Hell, a huge chunk of Pornhub was taken down a few years back due to verification regulation anyhow.
