Here is one interesting project that lets you see in almost real time leaked secrets (or suscpected secrets there might be fasle positives) across Github, Gists, Gitlab, and Bitbucket: https://www.shhgit.com/

You can also run your own instance: https://github.com/eth0izzle/shhgit/

It's useful but yeah a ton of false positives :) Most common false positives appear to be the test values.
