I just upgraded Google Community vBulletin. I thought they had better ways to fight spam, but not so: they use image verification, no matter how complex it is. The more weird-looking the images get, the harder it is for real humans to read them. Sometimes, computers can even read images (using OCR) better than humans can. So that’s not the way to go. Computers can crack images better than humans can, so we really need to focus on what computers cannot do. I think the next logical step is to ask a question, like a test you might have taken at school.
It’s simple, easy to implement, and very effective at defeating bots. I think it should be at least as effective as image verification.
