I was using image verification, but I just heard of a program that allows you to send them a picture and they send it back to you with the letters for $8 per 1000 images. So I decided to change that to random questions like "What is the color of grass?" that I saw on another website. Cross your fingers that this works. If you end up ever having the same problems you may want to change the registration verification way in the admin cp.
If anyone has any other ideas that I could try out, please leave some comments below!

That method has always stopped 100% of the automated spammers for me, human spammers will still trickle through from time to time though, not much you can do about it.
