WordPress on S3: how to prevent hotlinking

Now that you use Amazon S3 to store and serve media files in scalable fashion, how would you prevent undesirable hotlinking to your files?

Hotlinking to cloud storage URLs

Hotlinking (or direct linking, inline linking) is when other sites link to or embed the image (or other media file, e.g. video) directly without providing a link to the source page. Oftentimes hotlinking happens without meaning any harm: people just want to share a picture with their Facebook friends, or post it to forums they like or etc. Regardless of intention, though, hotlinking may be harmful to your business: the media file gets downloaded from your site and consume the bandwidth that you pay for, but the user doesn’t get to see your page depriving you of ad revenue, etc.

With WordPress-to-Cloud solution all media files are stored in the cloud storage such as Amazon S3. Now it is the cloud storage (and not your web server) that serves the images and other media files.

Here is the data I found on the AWS outages in the last couple of years:
