Oddbean new post about login | logout How can he afford to do this at scale?
With PoW he can still post 2-3 times per second, which is still enough to be persistently annoying. If we increase it so he can only spam once every 5 seconds, he will still be happy to do so, while users will suffer extreme slowness as they use the app. Basically I'm realizing PoW is not that good. A little doesn't hurt.
