I don't see why if I got my credentials right, I have to prove I am not a robot. What if I wanted a robot to access my account on my behalf?

I assume they’re trying to fight against bots buying up “hot” Airbnbs that sell out quickly. It’s a weird captcha for sure, but understandable why they wouldn’t want bots accessing the site.

If you have bots buying your merchandise as fast as possible you don't have a bot problem, you have a pricing problem.

Wait, what does a robot do once it rents a house?

It sets up a workshop inside to build more robots.

If I was a betting man, I’d wager the reason why they give these weirder types of challenges is because solving CAPTCHAs means you’re labelling them, which gives who ever is hosting it labelled data to train their own models against. that’s why CAPTCHAs sometimes ask ppl to spot all the zebra crossings and stuff etc - no machine can solve it yet, so ppl can do it, and by doing it and solving it, you produce a labelle…

That's how hCaptcha does it https://www.hcaptcha.com/labeling You play to get a dataset labelled and trained.

Except there are now enough labelled datasets of those things, even public freely available ones.

If you wanted to increase the precision of the model further, you'd end up using very ambiguous images which wouldn't be suitable for a captcha.

They probably want to reduce scraping and definitely unauthorized account access. In addition, Airbnb has thousands of A/B tests running at all times. Scrapers may try to decode pricing algorithms, price fluctuations, etc. The traffic and interest to an offering also has an impact on its search ranking.

There are also anon account crews that will make many fake accounts using sourced credentials from their social group or bought on darknets. Generally, those only result in things like pop-up events from which entry fees are collected. I assume some could use the same method to commit robbery. Another method is to use a botnet of fake accounts and use the bots to build up fake reputation, eg offer a fake listing, book the fake listing, leave good reviews, etc.

There are also some weird currency arbitrage opportunities that might be found if someone was really inclined. From what I saw of that aspect, you'd have to be really looking for pennies in the couch seams.

It's Arkose Labs (also used by Roblox, GitHub, Dropbox, Twitch, and more). There's some more links here: https://github.com/dessant/buster/issues/178 (Buster is a browser extension for automated captcha solving). You can subscribe here https://github.com/dessant/buster/issues/320 Their audio captcha (no longer available?) involved listening to 3 MIDI tunes and picking "the sad one".

It's probably no longer available because picking out "the sad one" just amounts to picking out the one in a minor key. Machines should be able to do that fairly easily.

Does this actually happen??

And why would they care if it did, if the robots are "buying" the properties, implying payment?

That makes the impression that Airbnb is always out of service, and the other platform selling Airbnb rent is more available. It creates a competitor and worsen the service of Airbnb at the same time.
