I think it represents nothing. You dont really know or learn someone's characteristics or personality traits from social media.We glimpse what a minute or short time in the life might be like from a photo or short vid that they choo se to show. Instagram is also easyto sign into by accident especially on older phones. It's possible to not realize if the account is public. It has taken me a long time to even know how to navigate all the site settings or options on some social media.
