But after you’ve completed the Anubis PoW challenge for a site, it remains valid for some amount of time.

So it’s not quite as horrible as it sounds.

I have setting up Anubis for my own sites on my todo list. And I wish more people did it too. I don’t really mind waiting a little bit extra every now and then before the page loads. What I do mind is ReCaptcha asking me to click all the pictures with buses in them etc. And especially when I have to do it several times over before it’s happy. I’d rather wait a minute for a page to load than to ever solve a ReCaptcha again, if given the choice.
