Kinda off topic question to google - when I do this labour of tagging your data so you let me use the internet - should I click on every box that has parts of the bus? Even if it's like one pixel?
Follow up question - why ask people to work when you can just say "pay 1 shmeckel to view this content" and then use this money to pay for data taggers?
Thank you for letting me use your internet!
I was pissed off at the same thing today.
I tried ticking every part - not working. Then I tried just the core. Not working. It took me 5 captchas until I got to one that had different images.
Terrible experience. Most of the time I just close the site now as I can't be arsed.
There's no specific "right" answer on the boxes. Like another post said they're looking at god-knows-what to decide whether or not to let you load the website.
Years ago I started to deliberately pick one or two wrong answers, or just not take the time to really look at them, and it made no discernible difference on how often I pass.
Recaptcha contains a whole maximally obfuscated virtual machine with its own bytecode language. It measures your mouse movement, clicks, timing, cadence, hesitation, consistency, tile clicking order, etc.
Ambiguous tiles are deliberately placed because the behavior they elicit from humans can be used to discern them from bots.
Yes, the "correct" reaction to the ambiguous tiles is to hover a bit indecisively. You need to waste a certain minimum amount of time on the CAPTCHA. I've found that applying videogame reflexes and zapping all the tiles in a short period of time is a fail, even if they're the correct tiles.
I think it depends on how much it trusts your ip address / user agent. I used to use an extension, nopecha, that would just use ocr and then select all the matching boxes, and it never seemed to get flagged; but I have a lot more trouble on a vpn ip like proton. These days I use buster to solve captchas and it works enough of the time that I don't have to fight with captchas.
My office uses ZScalar which most sites (especially Cloudflare ones) perceive as an "open proxy". The IP that Z's datacenter uses resolves to some place in Chicago. Some days, no amount of clicking on boxes works for their algorithm.
Is buster a browser extension?
Yes: https://github.com/dessant/buster
