In the end its her decision. But it will certainly have a big influence on her income.
I personally think, that she was never really passionate about the thinks she was doing for her site. She seems more passionate when she talks about fitness.
She always claimed to be naughty and do naughty stuff for her site but actually the stuff on her site is not really naughty.(only one or two b/g scenes and a lot of teasing videos where she flashes her tits from time to time
).
But thats just my personal opinion and its really sad to hear that she wants to downsize, because she looks very sexy with big tits.
