For example, IPFS "solves" this by allowing requests for takedowns per gateway. The upside of IPFS is that you can go after every host, the downside is that everyone knows what content you visit. The network still propagates the illegal content, so you end up with a witch hunt.
It's probably a good thing paedophiles haven't widely discovered IPFS+TOR.
The “witch hunt” aspect is no different than BitTorrent, right? Or even just people repeatedly uploading the same content to various online hosts and sharing links via any channel whatsoever.
IPFS would make it easier to identify non-modified content hosts since the hash is always consistent. It's far easier to bury something using standard HTTP or HTTPS or even FTP.
