Copyright issues are the easy end of the problem stick too. I'm going to straight up ask - what happens when a child porn ring starts using this?

It appears to already be a home to some fringe stuff.

"Big cities are like financial slave camps - Take a break at the Zenvow Meditation Resort - All crypto Meditation Resort in Portugal" (of course this is crazy, but harmless—at least initially)

I would also like to know what solution has been proposed for that problem.

IPFS supports censorship, theoretically.

Most likely, it will. But since it's decentralized, it would be hard to enforce copyright.

Probably not that hard. IPFS is not explicitly trying to hide your traffic. If you're seeding copyrighted content, your ISP can be sent whatever the country-supported legal papers are needed to punish you.
