Yes but if you make a mistake the capcha fails, hence they are already labeled.

- jre 5y agoI would guess they have a system such that after a user has passed N captchas successfully, they trust its a human and start displaying them (a portion of) unlabelled captchas that will always succeed and that's when novel labelling happens. Or something along those lines. And then you can get creative displaying same captcha to multiple users, etc...
- thargor90 5y agocaptchas mix classified and unclassified data. Only if you get the classified data correct a users data is used to classify the unclassified data. Also the same picture is shown to multiple people to improve confidence.
- Hamuko 5y agoThe first version of reCAPTCHA made it very obvious as to which word was the classified one and which was the unclassified one, so people had a pretty easy way to inject bad data into the process.
- Sohcahtoa82 5y agoYeah, I remember my days on 4chan where people kept posting a campaign to substitute a racial slur for the one that looked unclassified.
- Spare_account 5y agoOne of my hobbies is figuring out which captcha prompts are the unclassified data so that I can answer wrong and stick it to the man.
- _pebz 5y agoHow do you do so?
- BenjiWiebe 5y agoI just try to get one randomly wrong. It almost always lets me through. Also, I'll pick the wrong one that almost looks right. Say, a picture with a vaguely traffic light shaped mailbox or a train shaped car or something. :)
- rurp 5y agoI have noticed there's a very very low correlation between how hard I try on captchas and how quickly they let me through. I just quickly mash a bunch of tiles to start, maybe trying to be in the right general area. That works surprisingly often and when it doesn't I, and pay closer attention to what I'm selecting, then I pretty much always get through on that next try. This approach mostly fixes the annoying phenomenon where I carefully select the exact right tiles only to be told, "too bad, try again".

- hdjjhhvvhga 5y agoIf the manufacturer of self-driving cars decides to save money and depend on low-quality data, they should be blamed, not a random dude on the internet trying to send a form or visit a page.

- blue_cookeh 5y agoSome are already labelled, the user doesn't know so it's in their interest to solve the captcha properly and provide good data.
