How to stop bots from posting?
 

There's one product that gets about 10 new reviews every day, all from an anonymous, unregistered user, and all the reviews say the same thing. Is this a bot doing this? The IP addresses are all different. You can see what I'm talking about at this page:

Is there any way to stop a bot from adding reviews, while still allowing unregistered guests to add reviews?

If the ip address is different from all there is no way to stop them that i see as you allow anonymous posting which means anyone can post.

I have the same problem. My way: Moderate unregistered reviews. I delete alle the Spam and it never befores shows to users.

Any CAPACHA-Security would be great :D

captcha is a nice idea and easy to do
