Here’s the official explanation.
Reading between the lines, the reason is this: posting social media pictures and videos of herself in which she is waving her bare ass at the camera is not particularly helpful to support her case that she is a fully mature adult and can behave responsibly without a conservator.
This is bad news for those of us who support this behavior and encourage her to act as immaturely as possible, in the hope of seeing those pictures of her jiggling bare ass. I think, however, that her strategy will only be disappointing to perverts in the short run. If she gains total autonomy, we should soon see her acting totally irresponsibly.
As the good lord intended.
