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

      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.

        Not really... brute forcing with the most common answers would do just fine in most cases.

          Having a lot of questions (hundreds) would prevent this though. The questions shouldn't require the user to think or do research either. The Mercedes question above would make a lot of users do research.

          The whole point of CAPTCHA, whether its image, text or sound based, is to help prevent bots from registering while allow easy access to people.

            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.

              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.

              As I said originally, without the ability to use links or images in questions, Q&A as it is in vB now is next to useless. It might work for the time being because it's new, but that won't last long.

                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.

                  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.

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

                    I see and feel it on my forums!

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

                              Three questions, I know not much but I'm still "working" on it

                              How many would you suggest?

                                You have to think outside the box. Ask users to spell words backwards, or without vowels. That throws a nice spanner in the works. When you think of all the easy but different things you can do to the English language you actually have quite a lot of possibilities. And regarding your bruteforcing suggestion, one would assume that vBulletin blocks IPs from people making a ridiculous amount of requests to the registration form. I certainly do that in my applications
