Some thoughts on how useful Anubis really is. Combined with comments I read elsewhere about scrapers starting to solve the challenges, I'm afraid Anubis will be outdated soon and we need something else.

You're given the challenge to solve by the server, yes. But just because the challenge is provided to you, that doesn't mean you can fake your way through it.

You still have to calculate the answer before you can get any farther. You can't bullshit/spoof your way through the math problem to bypass it, because your correct answer is required to proceed.

There is no way around this, is there?

Unless the server gives you a well-known problem you have the answer to/is easily calculated, or you find a vulnerability in something like Anubis to make it accept a wrong answer, not really. You're stuck at the interstitial page with a math prompt until you solve it.

Unless I'm misunderstanding your position, I'm not sure what the disconnect is. The original question was about spoofing the challenge client side, but you can't really spoof the answer to a complicated math problem unless there's an issue with the server side validation.
