There are a lot of great plugins to prevent spam but especially the effectiv captcha images can annoy your human visitors. Geo Captcha uses the knowledge that a lot of spam is caused from a few countries and prevents them from spamming.
Visitors from the countries on your whitelist will never see a captcha image and will not be annoyed. Visitors from other countries will have to type in the captcha code or their comments and registrations will be blocked.
The location of the visitors is checked using the GeoLite Country-Library from MaxMind (http://www.maxmind.com). The captcha image is generated using SecurImage from drew010 (http://www.phpcaptcha.org).
