[QUOTE=Gamefreaks1234] The bots have become smart with captcha. There is one simple way to stop the bots. Have a randomized question. Simple ones like what is the capital of england. What colour is the sky. Bots can't get through these. Simple but incredibly effective![/QUOTE]
@Gamefreaks1234: You're wrong unfortunately. Spammers won't hesitate to pay humans to collect the (limited) number of questions and their answers.
Once the collection is done, any bot can use this dictionary and pass what is nothing more than a captcha.
