> hCaptcha’s solve rate meets a 99 percent benchmark, according to Khedouri, meaning that out of 100 users, 99 can solve the query within two tries.

That’s a 10% fail rate under standard independence assumptions. They wonder why people are freaking out.

For one of my ISPs (carrier grade nat), I get multiple captchas per hour, and frequently find my IP has been shadow banned. This is exclusively while reading the news and using paid accounts in long term good standing.

This is not what empirical measurements show. It is referring to a minimum internal benchmark, rather than what actually happens. (source: work there)

If you're getting shadow banned somewhere, it is typically either the site itself or their CDN or bot management providers that is sending you into a challenge loop; hCaptcha doesn't control the behavior in those scenarios.

hCaptcha has been making odd choices since before smiling dogs. I remember when it would give you a prompt; some kind of landscape feature, and you'd have to pick kind of similar landscapes, which never really seemed to match the feature. I'm also sure that such a thing is not accessible for the visually impaired.

I’m still struggling with Captcha to find that pesky 3 Finnish snipers throughout a snowy landscape.
