I don’t know if “anything”. But surely people overestimate its capabilities.
It’s only a PoW challenge. Any bot can execute a PoW challenge. For a smal to medium number of bots the energy difference it’s negligible.
Anubis it’s useful when millions of bots would want to attack a site. Then the energy difference of the PoW (specially because Anubis increase the challenge if there’s a big number of petitions) can be enough to make the attacker desist, or maybe it’s not enough, but at least then it’s doing something.
I see more useful against DDOS than AI scrapping. And only if the service being DDOS is more heavy than Anubis itself, if not you can get DDOS via anubis petitions. For AI scrapping I don’t see the point, you don’t need millions of bots to scrape a site unless you are talking about a massively big site.



I think the issue is that many sites are too aggressive with it. Anubis can be configured to only ask for challenges if the site is under unusual load, for instance when a botnet it’s actually ddosing the site. That’s when it shines.
Making it constantly ask for challenges when the service is not under attack is just a massive waste of energy. And many sites just enable it constantly because they can defer bot pings from their logs that way. That’s for instance what op is doing. It’s just a big misunderstanding of the tool.
