    I got that one through ReCAPTCHA... It's from a Chinese IP so I wouldn't be surprised if it's a manual signup.

    One of those spammers is registered with [email protected] email address

    How right! It was a question of "hours".

    I see and feel it on my forums!

    So far I had no problems with the Q&A function. Actually I don't even ask a question, I just ask the person registering to write down a word that I mention. I suppose that word could be randomly selected from a database, but as I said so far no problems using the one word.

    It was wrong to mention it!
    I have again over 10 new registered spam-members since yesterday even with random Q&A function!

    They register their accounts with "1" in required and not required fields and all born on January 01. 1980, with Chinese timezone and of course with different IP's. So there is nothing I can do.
    Not happy.

    But that's just it... even compiling a dozen questions general enough (but not dead obvious) that everyone would be able to answer them correctly is very hard, let alone hundreds. If you eliminate Y/N, colour, animal and calendar-related answers (which any bot programmer with half a brain would put on the list first), you're left with very little that is general enough that international members could answer. Heck, there's a good chance they'd get even those wrong, let alone anything more exotic or thought provoking.

    I was referring to the people writing bots to get around Captcha not human users.

    The entire post should be read to get the context there, not just that one sentence.

    captcha works great with freetype compiled into apache and ttf fonts enabled in vBulletin with a bunch of fonts installed and obsfucated a bit.

    There does not seem to be a warning in vB as to whether freetype is in apache, but I may have missed it if that is there.

    Using Recaptcha for now, there was no spammers before with captcha instead of now (i don't have any spammer)

    So it's not about the question itself but about the amount of questions? If I have this question:

    Does the Mercedes Benz 'Pagoda' have the engine in the front or in the rear?

    Is it easy to break or is it just easy to break when someone wants to break it?
    So far my forums haven't been the target of spam so I feel save but that can (and will) change…

    The only reason it has worked for people so far is because no one is targetting their forums. Why develop tools against it when all the big boys still use captcha?

    No, I still use CAPTCHA.

    I started using ReCAPTCHA for a while until I noticed nobody was registering, at first I thought it was because my site was new but it turns out ReCAPTCHA was messing up the registration page by making it so once you hit Submit it would try to download register.php instead of moving on (probably my fault, but eh).

    I switched back to CAPTCHA and so far no spam bots and everyone is getting through fine.
