ELI5: Why do strangers want to follow me on Twitter?

I have minimal interaction with social media (no Facebook, no online gaming, etc.), but I did sign up for a Twitter account just so I could follow a handful of organizations I'm interested in.  I follow about a dozen Twitter accounts, and I've never once tweeted anything myself.  Randomly, though, every few weeks I still get a request from some stranger that wants to follow me.  Some are just regular looking people and some are kind of porn looking with suggestive pictures/comments.

For someone not social media savvy, why would these people have any interest in following me?

They don't have an interest in following you, they're either ways of getting you to go to some site (like the latter group) or they're people who follow you in hopes you'll follow them so they can up their number of followers... for some reason this is valuable to people.
