You know what? You're right! You're absolutely right! We don't know about her motive, neither do we know if she cares about us, at all. But does that matter? If her motive is to attract new members to her site, then that's the way it is and we'll accept it.
But if her motive is to get a little closer to her fans, then why shouldn't we let her do it?
In any way, we are the ones who benefit most, because we get a little closer to her, so why think about something that doesn't matter in the end?
And the only thing you'll achieve with posts like these is to move her a little further away from you and me and if you really think, that "she is fucking hot and on with the pictures" then this can't be something, you wish to achieve.
Just something that came to my mind. (although some people might think of it as and invitation to offend me once more....)
