        Excluding Linux clients, as they are likely crawling bots…
    
    Is this why so many web servers assume I'm a bot? They often don't even give me a captcha, they just straight up deny entry.

    Should I put Windows or OS X in my user agent?

    When I heard about Spirit's liquidation today, I dug into their web infrastructure. After discovering that their entire booking flow and Azure API was left exactly as it was before their announcement, I grabbed 3 obvious phishing domains for $11.48 each to block malicious actors.

    It's like they didn't even consult an LLM on how to perform an orderly shutdown! Thanks for the interesting read, I'd be a bit paranoid registering those domains though you seem to have benign intentions.

      To be fair, if I’m working for a company that just went bust, I’m already an unsecured creditor who is probably facing a long battle to be paid what I’m already owed.

      I’m sure as hell not going a hang around for free to do an orderly shutdown of their IT infrastructure.

        That's exactly why I don't blame their IT team at all. Truthfully, the reason this story intrigued me was just how little preparation the higher-ups made beforehand. For a company that's been in a bankruptcy case since Aug 2025, you'd think they'd have made some preparations for the worst.

      Truthfully, I just felt that those three domains were way too predictable to leave open, especially if I wrote about them. I have documented that I have done nothing but redirect to their own site, though it might still be a risk.
