If they have a patreon I found something a couple of times on kemono, it wasn’t up to date but it was good enough for what I wanted to check.

Sounds good but, that makes me think, What about Pirate podcast ? (which is distinct from, also interesting, piracy podcasts)

Found some on country specific private trackers. You looking for American based podcasts?
