I had assumed in the anime captcha you were given an example of the character and told to identify all pictures of said character. Otherwise I couldn't do it.

No, it's a well known character.

  That's probably a generous use of the term well known

    "Broadly known in narrow circles" to be precise.

> A centralised ID system is one solution for authentication online but it's far from ideal. A much better system is a decentralized pseudonymous ID system where getting an ID is in some way expensive but still anonymous, e.g. proof of work equivalent to $5 in cloud CPU time. Then legit users can create an ID once and use it indefinitely, but also create as many as they like and replace them as often as they like for a relatively low price. Meanwhile spammers pay $5 for an ID that only lasts ten seconds before it gets banned and has all its messages retroactively deleted, so they go out of business.

  Attaching monetary value is one method but you always disenfranchise some people with systems like this. Cory Doctorow explores reputation based identity in his book "down and out in the magic Kingdom" but it seems this also has downsides (tribalism, manipulation of rep). It's a tough nut to crack. It goes under the term proof of individuality in terms of Blockchain.

    > Attaching monetary value is one method but you always disenfranchise some people with systems like this. This is always the claim but I don't really see it. Obviously if you put something on the internet then you disenfranchise anybody without a computer and an internet connection. But who is it that can afford a $50 device and a $10/month internet connection but not a one-time cost of $5 worth of CPU time?

      I guess CPU time is different to actually asking for money. But it would probably just skew so that CPU was incredibly cheap as spammers/bots mobilised to have as much CPU time on separate IPs as possible... Or something like that. There's always a way around incentive based methods.

If they had that amount of CPU time they would have the opportunity cost of using it to mine cryptocurrency instead, so it's still costing them $5 per ID.
