Don't forget, not every spammer is a bot. The amount of human spammers is ever growing, as bots find it harder to evade anti-spam technology like this.

@goforex: Try some harder or different questions - if you've kept them the same since you installed, then you're right, they probably have been broken. It doesn't take much to record all your questions, figure out the answers, then program a bot to automatically submit the correct answer. Keep changing them regularly - every month at least.
