Security Advisory: Microsoft Bing uses Cloudflare Turnstile for verification. This is a privacy-friendly, CAPTCHA-less alternative that does not require solving visual puzzles.
Note on Global vs. China Results: On the global version of Bing, you may occasionally see a "Deep search was interrupted" message. Despite this, the results are still optimal. This behavior does not occur on the Chinese version due to differences in how Deep Search operates there.
Legal Advisory: Regions outside of China currently either refuse to make traditional CAPTCHAs illegal, or they have laws against them but refuse to enforce them.
