#22What about Amex and Mastercard, do they have similar marketing opt-out forms?
apparently yes, but it does not work

#23The form doesn't require any sort of authentication, so I imagine someone could write a script to submit all (or a large portion of) the set of card numbers to this API. Might need to work around rate limiting and so on, but seems feasible?
There's an unspoken assumption here and elsewhere that the captcha doesn't present any kind of difficulty at all; is that true? If so, why?

#24Here's an equivalent form for MasterCard: https://www.mastercard.us/en-us/vision/corp-responsibility/c...

Most open source text captchas have ML/DL or OpenCV OCR solutions and more advanced captchas like gcaptcha/hcaptcha you can send to a solver farm like 2captcha. The cost for the farm solutions is pretty cheap.

#26Jesus Christ no accessibility on the CAPTCHA and even I failed it 8 times.

I'd only seen relatively pricey solver farm solutions, hence the question. What constitutes "cheap" here? For a baseline, .05USD/captcha seems not cheap to me.

#28So all I need to do is provide my full credit card number in this random page and then it'll opt me out? And this was somehow brought to the front page of Hacker News? This is a very low effort scam. At least put in some effort beyond your dozen shadow accounts on HN.
Domain and cert are visa. So at least you know you are talking to Visa so it’s not really entirely random.
Technically to someone who has demonstrated control on visa.com at the time the cert was issued. It doesn't necessarily mean its actually visa.com.
Although I didn't check to see if they're using OV or EV certs.

In addition to domain+cert verification, you can type in "visa.com", scroll down to the footer, click "Privacy", scroll down to and click the "Visit Additional Privacy Information" button, then read the last paragraph of the second-to-last question, which links to this same page.

I'm surprised Visa is using cloudflare for their certs.
