To make the data live after the original node goes offline, you have to push your data to random nodes which also push to random nodes.

Your node blindly accept data, store it and upload it.

There are some P2P network implementations which did that and failed horribly bad on the end. A few abuser can DoS the network.

Oh and there are illegal data and numbers. I'm rather extreme freedom-of-speech advocates myself. But even for me, there are some immoral data I will never help spreading it knowingly.
