Spambots pass Q&A verification: how to analyze how?

[renep]

I'm using Q&A human verification on my 3.7.0 forums. Unfortunately, I'm already seeing new spambot registrations posting the usual auto-generated spam.

I'd like to know if spammers have found a way around the system, or if some of my questions are too easy and are guessable by bots. Is there any way to find out what particular question a member has answered when (s)he/it registered? Can this be logged?

are the questions common knowledge? I'm guessing the spambots are using OCR to read the questions and then just referencing a database.

What kind of questions are you asking?

I'd rather not try to analyze it by guessing. What I'd like to know is: is there any way to figure out what particular human verification question a member has answered when he registered?

Sorry, there is no function to do this. This requires modifying the code. We cannot officially support code modifications or forums running modified code, however you can try searching or asking for help with this over at www.vbulletin.org.

Okay, thanks.
