Is Ayu hated in Japan?

[Taishaku]

This subject has always been kind of controversial. Most 2ch users are known for being very negative when it comes to Ayu. If I'm not wrong, some people also hate the fact that she was discovered at a young age and she didn't have to study a career and get a normal job like most people do, and some Japanese people think of her as an old brat and laugh that she's sometimes called "Ayu-chan" even when she's on her early 30s... And don't even get me started on Youtube comments.

So, like most artists, even if she has thousands of fans, she also has people who HATE her with passion.
How do you react to this? And why do you think some people hate her in her own country?
