Look, the answer is simple. She makes more than $5 million a year on her website and its sales and her customers sending her "gifts" alone. She isn't going to change her tune on that sweet deal. So what could change this besides age and a declining fan base? That's the key to forcing her to step up her game and show more. Say if an old boyfriend or one night stand or somebody has some pictures or videos of her naked or worse (fuck video perhaps) and posts them all over the internet. Now, those would catch like wildfire and once the numerous fans who are getting tired of her boring same-old stuff find her harder material released, they won't go back to paying for boring as hell non-nude shots of her going shopping or bullshit anymore and demand her to do more nude or harder unless her main cash supply runs dry.
Simple as that.
