Idk, funny that the one pic she re-uploaded then, was the one where the bum was more covered (by being cut from the frame). Sure that i'm not 100% saying that she removed the others cuz "got shy and regret reveiling the bum so much", specially when she still have that ppv one where the lower part of her boobs are naked, which is, imo, comparatively a more "hardcore" photo for someone who regretted some bum pics thus, if was about regret that ppv one should also get deleted. Or no...maybe she is ok with showing the lower part of her boobs and not exposing her bum so much.
Anyway, we have to see what will happen, if she will put the bum photos over an extra paywall, then your theory will be right. Although it will look like a scam if she re-uploads the photos that she already had not behind ppv. Well, if it was not regret and just an adjustment of strategy, she may forget those "old" bum pics and will put new bum ones behind ppv, to avoid some "scammy" feeling.
That's why i think the uploads people do here, they could just type "ppv" above or below the photo in case it's from ppv, just so we can start to distinguish what she posts as normal content and ppv, cuz it's starting to get confusing.
For example, the last upload here, her with a red bra, ppv or not? 😅 At this point i can't tell, thus why me saying in case it's "ppv" content, people could type ppv with the photo from now on.
