I use them at work as a cache during data ingestion phrase (analytics). I have to store a unique URL for each page the user is at, and each page generates a lot of requests. So I store the URLs inside a Bloom Filter, hitting the DB only when the contain() returns False. It's a neat little thing that saves me thousands of unnecessary database hits per second.
