went to school with her both high school and college. you are like half correct. ive never not known her to do tons of drugs and just be kinda trashy in general.
We need to start using different words than 'scammer' when referring to models who slow play their content rollout or who haven't reached a nudity checkpoint we think they should have reached.
I'd like to say it's probably a teasing thing or in the scenario you said, she's worried what people will think about her nipples/areolas. Women do be overly self-concious about their intimate parts as much as dude's who worry their dick is too small when in reality it's normal.
I feel like she probably just doesn't want to get played out. Everybody tunes in to see when she will star doing full nudes or full porn, but once it happens she'll probably lose a lot of that viewer base she accumulated. We've seen it happen with other creators, so I wouldn't be surprised if she just never does full nudity.
