I'm not sure how someone not checking and confirming their email address once a year is going to motivate anyone to do anything, other than be sure they use an email address they intend to check once in a while.
How do I get rid of illegal domain squatters?
There are good reasons for centralized systems.
Namecoin is decentralized.
It makes me remember a short paper from 1977 by Carl A. Sunshine [0] where he proposed a network architecture with no global unique addressing, no global routing, and no global naming. These three major axis of modern Internet censorship would fall apart.
David P. Reed, the designer of UDP, tried to push for larger role of source routing in the then nascent Internet architecture. But, somehow, it didn't reach what he had envisioned.
The 70's were a very interesting era on the research of networking fundamentals and I find it sad that such important topics like source routing weren't investigated much further in the following decades.
Shouldn't we somehow return to the fundamentals of networking to try to find ways of dealing with the censorship by the status quo against the natural need of sharing our digital culture in a free and anonymous way?
