Odd, but not unheard of. I've been seemingly randomly blocked by a couple girl's accounts before myself. I never commented on their posts, like ever, only liked them and one day was blocked. Even accounts I'd followed for years.
two different things, showing off her body parts may not be a problem for her because it may be something she enjoys doing but putting a price on it and constantly promoting it is something she may feel low. So no, I don't think she will ever make OnlyFans, especially since I think she comes from a wealthy and religious family
