I agree with you, I don't like keycaptcha cause it is a third party. It has stopped the spam bots, but it is still allowing human spammers, mostly from china. I am moderating new registrations and it is an annoying amount of extra work.
I am going to switch to LancerForHire - Paid Registration [and Anti Spam!] and charge a one time fee of 49 cents for registration. I hate to do it, it will definitely discourage casual members, but my site is very well established, a niche site, and I am hoping that people who care to join will jump thru the paypal hoop. We will see.
Any opinions out there? Have you found anything that defeats english speaking paid human bots? Adding an image, and asking questions about it, like Rackspace does, won't help with these spammers. I want to avoid moderation, although it is the best thing. It is quite labor intensive.
