^ Honestly Max adding in 2-3 new profile fields using images and regular expression have cut down spam registrations on several sites I admin on by 99%.

What I do is make anywhere from 2-3 (on some sites like my own I did 4, overboard perhaps but been spam registration free for quite a while) new images, I make it slogans or even take the sites logo and blur all letters but one, then using regular expressions in the profile field ask the user "Please enter in the letter not shown in the picture above" and they can enter in just one letter lower or upper case so for example if in the image it shows an "N" the regular expression would be ^[nN]$ so they can enter in "n" or "N" and it will accept the answer otherwise it will not and having that one field incorrect will deny registration. *New profile field must be set to "Filed Required: Yes, at registration and profile updating" & set the default value to be an incorrect answer so if the spambot simply tries to blindly submit the page yet one more way for it to fail.
