As an success example of stopping spam to be a problem - look at Google BigTable.

Has YouTube problems with spam? No.
Does it care about single video to be re-uploaded thousands of times? No.

Bigtable consists of millions cheap servers with regular SATA HDDs. I want this to be implemented in Bitcoin. It will make Bitcoin very powerful and scalable and stop spam to be a problem at all.

All your examples are highly centralized services.

If you want to build something decentralized, that is difficult to shut down or game, then it will look different than those examples.

Bigtable was not built to check for cheating in those millions of cheap servers
