Keep increasing the PoW cost and think about where that line of argument leads you. "One message delivered to the inbox is worth far more than a billion messages delivered to the spam folder." One single delivered message is going to be profitable for the spammer? Clearly not. This proves the existence of some break-even point at a lower cost. Mail providers just need to set the cost above this point.

That doesn't make sense. Each email is only worth so much to a spammer. They can't lose money on every email and make up for it with volume.

The paper's argument assumes that the PoW scheme is required though. It could be an option which just guarantees that individual mail can get through, while still keeping the usual reputation-based spam filtering for clients which don't want to participate.

I guess the idea was too obvious to be original. I'm surprised that it inspired Bitcoin instead of the other way around though.

It would be nice if these big mail services accepted actual proof of work as a way to guarantee that your mail gets through. Maybe someone could extend SMTP with a bitcoin-like challenge where the server sends the client a nonce and a difficulty factor, and the client has to reply with a suffix that you can append to the nonce so that the whole string hashes to something with the corresponding number of zeroes at the end. People sending personal emails will be happy to burn a penny of CPU time as "postage" but spammers won't be able to send their spam profitably, especially if you increase the difficulty factor based on how many emails you've sent in the last hour.

What are you saying is the connection between GitHub's acquisition and this header? This code is from git, not GitHub.

Currently the Linux kernel computes a score for each process based on some heuristics. There's a good introductory article on LWN:

Well, it's open source. Are there mysterious binary blobs that I'm not aware of? If not, then when this becomes Google's new mobile OS then it's going to be the same as the situation today with AOSP running a bunch of untrustworthy closed-source Google services and apps.
