The ultimate captcha
Finally the antispam industry came up with something working, instead of creating an unreadable image with words that go all over the place, create something that only humans can recognize. The most famous example are "The Rapidshare cats". A poll on our homepage showed about 80% hated them, but they have no idea what poor RapidShare is going through with the captcha crackers.
A common question is "why not just add two pictures, cat and dog, and make the human user select which one?". Well, the answer is simple: if spammers have a success rate over 5%, they consider it to being profitable. So, that's why they combined it with the old textbased captcha.
Personally, I believe the idea is awesome, but the realisation could have been done better and as usual: less annoying for the end user. Maybe they should try to implement some sort of rotating system showing different types of captcha's all the time?
