moot, founder of 4chan has made it very clear in the past "No, we will never implement a captcha." It wasn't until the social virus was released on 4chan that uploaded itself, along with any random file it happens to find in Documents or other sensitive areas publicly, that the captchas were put in place. This evolved to the point where they started selling 4chan as a service without a captcha (I'm actually all for that). Sometimes there is just no way around the problem.
