@cartocalypse@norden.social @drgeo@mamot.fr @doctormo@floss.social Right, I believe how the likes of Anubis work is they basically make the client calculate a proof of work problem, for a normal user that means starting at page for some seconds, maybe heating up their device slightly if it's a mobile/thin and light but it's usually fairly painless.
For a bot however it makes it a lot more expensive to crawl the site.

@Dragon@toast.dragon2611.net @cartocalypse@norden.social @drgeo@mamot.fr @doctormo@floss.social That's the idea, but since you do not have to do it for every page and you can do the PoW much faster outside Javascript, passing Anubis is probably a negligible cost: https://lock.cmpxchg8b.com/anubis.html It probably works due to other factors like crawlers not executing arbitrary Javascript and not implementing a fast workaround due to only being used on a small number of sites.
