Sounds like a great idea to get rid of #captcha - rather than nag people to solve silly riddles on each page separately, have a cryptographic and privacy-preserving protocol specifically for proving you're human. From user's perspective this works pretty seamlessly, under the hood there's some interesting crypto and proof-of-work protocol.
@kravietz that looks very interesting. I'll have to dig in and figure out the details.
@mister_monster @kravietz i don't really see the point in attacking on bots in the first place. Bots normally scrape text not images, and it's the images that consume a significant portion of bandwidth.
From my perspective it's not about scraping bots but about spam bots - you put any contact or registration form on the web, and within a week you start getting tons of spam messages every day.
@kravietz @mister_monster That's a fair point for some sites -- but search engines and airfare sites are also using #CAPTCHA even when there's no form to submit, which must be to block scraping.
In case of Google it's most likely due to prevent free programmatic use of their search engine which they also sell as a paid API.
@kravietz @mister_monster that's #Google's excuse, but what about qwant and ecosia (who get their results from Bing)? I suppose for them it's about stopping ppl who avoid the ads.
