MicroID - Small Decentralized Verifiable Identity

I am not sure what to make about MicroID. The problem is that the paper does not really seem to explain how the technology meets the intended use cases:

MicroID = sha1_hex( sha1_hex( "mailto:user@email.com" ) + sha1_hex( "http://website.com" ) );

This provides me with a way to prove that I developed the content, but only if a plagarist did not strip out the MicroID.

It does not provide me with a way to repudiate a third party claim that I created content I did not create. Anyone can create a micro ID for anyone.

It does not provide me with a way to find the copyright owner.
