Why would a girl follow and unfollow a guy on Instagram?

Anonymous
She has done this multiple times in the last couple of weeks. I don't even talk to her. I haven't seen her in years. It just seems odd.

She will post a new picture than refollow me a couple hours later. Is it just to get people to look at her account and like her pictures?
