I came across one of those recently - I'm sure it was a particular hardware vendor site and was required to download a driver or firmware but can't remember which.

It took me several attempts as "crosswalks", buses and traffic lights look very different here and pictures were small and grainy. google have mastered the art of creating intrusive annoying obstacles.

Bingo!

That or instead it's interpretation and nearly every block can be said to have a crosswalk or whatever they're asking for.

SOLVED

Um... if you're trying to mark the thread as "solved", see the Thread Tools menu.

That is clever

LQ uses the crosswalks, vehicles, etc. Newer implementations use the boats. I haven't seen the ones you describe since years ago, since they aren't used to train google's self-driving AI models.

I expect you're right. Google's captcha wasn't the only captcha just like most sites were not using cloudflare or google analytics or google apis, or entangled with social network trackers. FAANG have wormed their way into most of the web - creating dependency - in fact doing far worse than what MS could ever dreamed of doing in the late 1990s. MSIE bundling pales in comparison to the current situation (from my perspective it was never an issue to start with).

As with DNS over HTTPS, captcha is one of those liberty/security trade offs. As I have said before, these surveillance, profiling, data mining, "research" methods may be very secure - in that they securely transport your data to those corporations harvesting it, but in terms of privacy - which should be a right - that's almost non-existent.

As well as training self driving vehicles, captcha makes google a "gate keeper" of sorts to capture data about users who visit certain sites.

Maybe I'm overthinking. When the captcha asked which of the following were boats, I looked and said, "No, that's a ship. That's a ship..."

Has anyone else mentioned that captcha methods don't work on older browsers. I, for one, am still able (for now) to log in to LQ to ask questiuons and post replies. But i can no longer upload any file attachments because the captcha service doesn't recognize any of my browsers.

I don't see any captcha when attaching files.

Where exactly are you seeing it - when pressing Manage Attachments, when pressing Upload, or when posting?

Attached Files

test.txt (4 Bytes, 7 views)

Today i no longer see the captcha window. A few days ago what happened was i was able to press Manage Attachements, browse my system for the file to upload, and when i pressed 'Upload', the little 'Manage Attachments' window became a Captcha window that told me to wait as it checked my browser. It did give me a button to press that said 'I am a Human', but then timed out or something without ever giving me an image to look at, nor would it upload the file.

I worked around the difficulty by simply loading the file onto my own personal site and providing a hyperlink to it.

Whatever was going on now seems to not be a problem.README.txt

Nope, the Cloudfare security is again preventing me from uploading attachments. I can click 'Manage Attachments', and browse my home system for the file to upload, but when i click on 'Upload', the small upload window converts to a Cloudfare window which says in big letters:

One more step
Please complete the security check to access www.linuxquestions.org

and a bunch of explanatory text, but never gives me any captcha images or text. The file to upload is a .txt file of about 32k. Am using an old Firefox browser 3.5.6 (c) 2009, with which i can still do almost everything else in LQ. With Opera 11.61 (c) 2012, it gives me a "I am Human" checkbox, but nothing happens when i click it.

You're using two obsolete browsers... time to upgrade.

For what it is worth, I have not seen a captcha window, but I have twice seen a Cloudflare window/overlay which clearly identifies itself as being Cloudflare with a message and progress indicator about "Checking your browser". They were unexpected and brief so I did not get a screenshot or copy of exact wording in either case.

This with Firefox 68.12.0esr on Slackware 14.2.

I am certain that one occurred during a login attempt, not so sure about the other one.

I know that my case is not the same as dogpatch's, but assuming it was Cloudflare and not some other MITM attack, they obviously do inject themselves into our ordinary requests in unexpected ways. Who are they to "check" my browser, and what exactly are they checking for?

Is this new LQ policy, or just your opinion? I hope it is the latter. Everything else in LQ still works fine for me (so far).

My question as well.
