How did the old BS index work?

The retired formula gives 3 Weak × 100 + 3 Mixed × 50 + 0 Solid × 0, divided by 6 rated questions = 75 after rounding. Unknowns are excluded. It is an editorial shorthand, not a measured probability, so this dossier leads with individual findings instead.

The six questions

  1. WeakLaunch claims vs independent tests

    When they say a model is better, faster or cheaper, do independent evaluations agree?

    Cloudflare said it caught Perplexity's crawler switching to a disguised identity after being blocked, in an attempt to bypass site owners' preferences, activity it said it fingerprinted across tens of thousands of domains; Perplexity called the report a publicity stunt.

  2. MixedMoney claims vs the filing

    Do their valuation, revenue and user numbers survive contact with primary disclosures?

    Perplexity's annualised revenue rose from less than $250 million at the start of the year to more than $750 million as it discussed a new funding round that would value it at more than $30 billion, an increase of more than 50 percent from its prior valuation.

  3. MixedPromises kept

    Did the things they announced with a date actually ship, on time, as described?

    After being sued for allegedly copying content without permission, Perplexity launched a Publishers' Program promising revenue sharing, later backing it with a $42.5 million pool and an 80% split under Comet Plus; publishers who never joined the program, including the New York Times and Japan's Nikkei, kept suing anyway.

  4. WeakSafety and incidents

    When something went wrong, did they disclose it quickly and honestly?

    Security researchers found Perplexity's Comet browser vulnerable to indirect prompt injection that could expose emails, banking passwords and other sensitive data in August 2025; two months later Brave disclosed a separate set of prompt-injection vectors in the same browser, using hidden text in images to hijack it.

  5. WeakTransparency

    Do they publish what an outsider needs to check them?

    Perplexity published a list of its crawler IP addresses as a transparency measure, but WIRED found at least one undisclosed IP address still being used to access pages that had denied it permission, which prompted AWS to open its own investigation into whether the crawling violated its cloud rules.

  6. MixedLegal and regulatory record

    What do courts and regulators say about them?

    The New York Times sued Perplexity in December 2025, alleging it copied, distributed and displayed millions of Times articles without permission to train and power its products, joining a growing list of publisher lawsuits that already included Dow Jones, the New York Post, and Japan's Nikkei and Asahi Shimbun over the same conduct.
