I have seen very painfully long proof of work demands by Anubis on thebrainbin.org.. not sure if that is triggered by a Tor exit node IP. Now I get access denied from Anubis, for the first time ever, when visiting quokk.au. Hope it’s not going to become a trend.

When a CAPTCHA or proof of work tool

That's not what Anubis is. They're an anti-bot firewall. You're the one who decided they're something they aren't.

    Marketing works wonders on people. My devices are doing a lot of work when Anubis presents, to produce what you claim is not a proof-of-work, that is for some reason a barrier to entry. “Firewall” vaguely refers to perimeter security -- not even web-specific. If you think my browser is just waiting around for for an open slot, this does not explain the time lapse consistency. Please explain why “Calculating...Difficulty: 6,…Speed: …kH/s” is presented, if this is not a proof-of-work. Looks like kilohashes to me.

    Anubis is a software intended to stop bots that uses proof-of-work as one of the tools in its toolkit. That is different from it being a proof-of-work tool.

    This is a fallacy of division. It encompasses a proof of work tool. Yet it fails to use it properly to get better accuracy. It doesn’t matter how many tools are in that toolkit. They are not being used sensibly.
