By default Aha automatically filters and blocks explicit content for you. If you would like to enable the ability to listen to explicit podcasts, as well as comedy or user-generated shouts, you must enable the option to allow explicit content.
To do so, tap the hamburger stack (triple hash) button on the top left corner to reveal the slide out menu.
Go to Settings and turn ON the Explicit Content option.
If you attempt to play an explicit podcast without first enabling explicit, you will be reminded that your settings need to be updated.
In other stations, where explicit content may be mixed with non-explicit content, the explicit content items will just be filtered out entirely.
