reCaptcha alternatives (9)

I was wondering if there were any alternatives to Captcha/reCaptcha, preferably ones that don't require user input.

My own website is slated to use captchouli at some point in the future.
You can also use a hidden input field that a user would never interact with, but a bot would send an input to. Then you can safely block all requests made from that input field.
That's hardly foolproof, but the only reliable ways that I know of that do not require user input are JS-based and make determinations using analytics. So basically, what you're asking for is botnet.

i think he means text input... not that multimedia captchas are any better. i would much rather have a lightweight textbox like on here than google's horrible mess
