That's the only concern I have about IPFS.
Just use Arweave sites as your nodes and your podcast will be untraceable.

Never even heard of it.
It's a protocol that creates decentralized websites in locations across the world.
You can run a node over tor but it's not recommended because your node will be harder to find (by other nodes).
Haven't heard of arwave either. Something like qortal?
Podcasters want to be found by nature : ) Untracability isn't much of a concern in podcasting (IMO).
