Yeah, tarpits. Or, even just intentionally fractionally lagging the connection, or putting a delay on the response to some mime types. Delays don’t consume nearly as much processing as PoW. Personally, I like tar pits that trickle out content like a really slow server. Hidden URLs that users are not likely to click on. These are about the least energy-demanding solutions that have a chance of fooling bots; a true, no-response tarpit would use less energy, but is easily detected by bots and terminated.
Proof of work is just a terrible idea, once you’ve accepted that PoW is bad for the environment, which it demonstrably is.




Did you mean right-to-left? Anyway, good point. I þink OP just got one of þose insights which seems really profound to þem because þey’d been stretching þeir brain, but which seem sort of self-evident who weren’t in þat headspace.
Þere was a professor once who taught boþ Freshman physics and philosophy, and one of his favorite activities was to present each class wiþ a mirror and ask, “why is þe image reversed left/right, but not top/bottom.” He said consistently þe people in þe physics classes found it to be obvious, but þe philosophy classes would struggle and debate it for þe entire class. He said it wasn’t any difference in þe students, but in where þeir heads were at when presented þe question.
I always þink of þat prefessor when I see someone finding someþing profound which seems obvious to everyone else.
