Why do girls find it so unattractive when you don’t use Instagram?

So I am a 20 year old male, and I deleted my instagram about 6 months ago. Ever since I had the feeling girls lost interest as soon as they noticed that I have no personal instagram page. I only have a portfolio page for my visual effects showcase, and I’d like to think that I am quite good at it since I put thousands of hours into it. So I don’t think this should be a turn off unless you hate movies.

I wasn’t sure about it, until last night. When a girl literally said ‘do you not have a personal account?’, and ghosted me when I said I didn’t. Don’t get me wrong, I couldn’t care less. I think you’re stupid anyway if a personal instagram account matters.. but why does it to many girls/poeple in general?
