Released my first crate ~20 hours ago; already downloaded 12 times. Who would know about it?

Howdy,

I released my first crate on crates.io yesterday and haven't advertised it or even started using the crates.io version in my code yet, but the crate has been downloaded 12 times. Is there some sort of audit process or automated caching that goes on with crates that would cause this to happen?

Thanks!

Edit: thanks for all the great replies and theories, it helps give some insight into the crates publishing part of Rust.
