I guess it makes sense to try to "clean up" a bit when you start to actually live off your reputation with tens of thousands of people following your online presence. Back when she was no one, she could do more or less what ever without consequences.
no one knows why or who she sent those pics to. anyone who says they were sent to mods just read the lolcow thread or some other message board. they were literally taken before she had any major social media presence around 2013-2015.
The floral dress pics really give some breedable energy, but dont be fooled, her tits are not that big. You can clearly see on cosplays like Officer Caitlyn or Jynx where she uses a non-padded bra.
