No, that doesn't add up: You only host data that's already available on a public network, pretty much by definition. If the rights distributor didn'f want it to be globally accessible, they wouldn't have put it up on IPFS.
If you doubt me, see all verdicts for infringement when bitorrenting.
You have no guarantees that the content put up via IPFS is by the original copyright owner.
Thus immediately after you receive the infringing content over IPFS and start seeding it, you are infringing on the copyright owners rights. You have no recourse and no legal defenses to protect you.
