OK. I think I heard somewhere that you can pay a relatively low fee (only once) to get your content hosted, which seemed a bit fishy to me, which is why I still remember it.
If that only means that I can find someone who hosts a node, and he can promise to host it indefinitely but he can still delete it when he wants, then I feel I have been lied to.
Filecoin is built by IPFS team and tries to address the permanence issue.
