Even if that were true, the post is very clearly advocating a change to Bitcoin itself. Don't you think it's just a little weird to suggest a technical change to a software project on a random blog, rather than discussing it first with the people who actually manage the project you're trying to change? Cryptocurrencies are also a far more specialised field than spam prevention. The blog post outlines a strategy for dealing with large mining cartels in a widely-used cryptocurrency. I'd suggest that maintaining a serious crypto-currency is something that very few people in the world have the expertise to do reliably. When your intended audience is, at most, a few thousand, or maybe even a few hundred cryptographers, I really don't see the point in putting it on a blog to a general audience.
