My website is being bombarded by registration spam and as much as I don't like to do it, I will have to setup a captcha to stop the automated registrations. I know the captcha will have some effect on the conversion rate for real users - but I don't think this can be avoided.<p>What do you guys think is the best captcha service which does not add too much of a barrier to user registrations?
Anything but reCaptcha. I'm pretty sure I'm a completely legit human, yet I can't decypher recaptcha 95% of the time. This is the biggest turn down of the whole interweb.
Just use a a challenge/response question.<p>What is the hottest season?
What is the coldest season?
Capital city of the UK?
What are the last three letters of the capital city of the UK?<p>.. and so on.<p>Better still to select a question specific to your usergroup.<p>Regards

I really like these guys (<a href="http://solvemedia.co.uk/index.html" rel="nofollow">http://solvemedia.co.uk/index.html</a>) I think it just makes it more interesting... and hey you may even make a bit off it. But I think reCaptcha is becoming impossible to solve
Has anyone used <a href="http://textcaptcha.com/" rel="nofollow">http://textcaptcha.com/</a> or a similar service? I really like the idea - a self hosted solution would be great.
