Does liking pictures on social media actually indicate whether or not someone is interested in you?

Do you think that if someone likes you, they'll inevitably 'like' your posts on social media? When you have a crush on someone or are interested, how is your social media behaviour different from people that you're not interested in? Have you ever dated someone or had a crush where you didn't like their posts?

And if you notice someone liking your posts on social media, do you tend to assume they're interested or at least attracted to you?
