How to disable Last.fm scrobbling?

It looks like Last.fm app is scrobbling every podcasts listened to in Podcast Addict.
Podcast Addict player is based on default Android API and Last.fm has a setting enabled by default that scobbles information about every app based on those API.

If you uncheck "Scrobble Android player" in the Last.fm app settings, then it will only scrobble radio plays.
