It's really common now for phishing kits to use interstitial pages that require solving a captcha before the actual phishing content is shown
Victims just click through the captcha without thinking, but it makes automatic verdicting by security scanners a pain because they just see a captcha page: can't tell the brand being impersonated, or even if it's a phishing site
