reCaptcha de Google. Captchas gratuitos que puedes usar

Los que usamos, tenemos o creamos páginas web tenemos que aprender rápido lo que son los Captcha.  Pequeñas pruebas o tests que se ponen en formularios (principalmente) para distinguir si quien lo envía es una persona o un robot (spam).

Nota: Para el que no lo sepa Captcha son las siglas de Completely Automated Public Turing test to tell Computers and Humans Apart. Es decir, test de Turing automatizado.

Como todo los Captcha han ido evolucionando, y Google ha sacado un servicio llamado reCaptcha. Lo que nos interesa no sólo es que sea bueno…es que además es gratis. Como dice es fácil de implementar para el desarrollador, fácil de usar para el cliente de la web y se va renovando y mejorando.

Manera de implementarlo:

WordPress: Podéis usar plugins como este.
Prestashop: Aquí tenéis cómo hacerlo por código. Y también tenéis módulos de pago.

Para el resto de Webs Google te deja un manual sobre cómo usarlo (es muy sencillo, generar la API, poner por código el widget y comprobarlo).
