[...] The majority are from bots and most now can crack a Captcha. What has proved to be most effective is having a simple questions and answer, I just have four that randomly rotate on each sign up. Haven't had a single spam sign up since I done it.
When they crack that, http://textcaptcha.com/ is probably the next step.
I quite like this one:
http://random.irb.hr/signup.php
But then it may discourage some real signups.
