Why would she delete me then re add me?

Ok this girl added me on Facebook and Instagram, she seemed to have quite a high attraction level for me because she was messaging me a lot, then she stopped messaging me because I didn't seem interested and she then deleted me off Instagram (unfollow) and Facebook, but then yesterday she followed me again on Instagram just out of the blue?

I don't usually go on social media because I only message to arrange dates etc.

Any ideas? :)
