> There's no asymmetry at all: you're just adding a fixed cost to each reward, for both users and abusers.
replyThere is: users solve the PoW once, scrappers solve it every time they rotate IP addresses. Some of them change their IP address on every request, so they keep solving the PoW over and over.
That doesn't matter! Every time they successfully solve the challenge, they're getting the token reward. That's the missing asymmetry. In an anti-spam system, 99.999% of all transactions are unrewarded.

replyI wonder whether what Anubis is doing might be blocking agents that do not run JS or that have a timeout (or humans who give up as I just did)
replyI suspect that's most of the value, and that the deterrent is about software construction and not about the proof-of-work, which I've been saying for the last year is a productive direction for Anubis to head towards. Instead, it's just sort of tormenting normal people, as a kind of performance of anger about AI.
replyWhich: I get! If it's your site, perform all the anger you want.
I have a small personal site with an exposed Git repository. I'm getting crawled from about 100000 residential IPs from several ASNs (mostly in Brazil). Each crawler makes a couple of requests per minute.
replyAnubis doesn't really help against this.
