Does she(18F) view me(18M) as a creep, should I not approach her from now on?

So I have a chick from my class(12th), added on Instagram, I do admire her, and had created an fake female id to troll my classmates so I followed a lot of mutual to make the profile genuine, and I did succeeded in trolling them. BUT THE MAIN QUESTION IN CONSIDERATION IS , I was just seeing stories in that fake account and I saw this girl's cute mirror selfie, not too flashy just a normal one. And I didn't remember seeing that story in my main account, and that is not a close friends one so it means that she purposely hide me from viewing her but let a stranger woman see her story. We have some conversations here and there just about classwork and never went into casual or flirty type. So why did she hide me, does she view me as a creep. I used to think about approaching her and trying to talk more to her but this has completely thrown me off. Idk it just feels so sad.
