[ Other - Games & Recreation ] Open Question : How can you tell if someone who asks you an anonymous question on Tumblr is following you?

I've recently received a message on Tumblr from someone claiming to love my blog. How can I tell if they're following me or not? If they're following me, shouldn't I have the option to reply privately? Thanks for your help (:
