Attention! This module is not supported.
This module uses the outdated Google reCAPTCHA API v1.0 and is replaced by the new Google reCAPTCHA module. Although Google no longer provide access to API v1.0 to new users, you may continue using this module provided you have working access keys created in past.
This module uses several methods of preventing SPAM bots from completing forms on your website and creating fake user accounts.
The supported validation methods are:
The module adds a hidden field which legitime users will never complete, but SPAM bots will try to fill in.
AntiSpam module signs every protected form with a unique number. So, bots cannot mass-submit the forms without reloading the actual page contents.
Submission delay check.
No one can complete the registration or the contact form faster than in a few seconds. If that is the case, the visitor is likely a SPAM bot.
AntiSpam module integrates with the free reCAPTCHA service offered by Google, but uses it only as the last line of defence. Honeypot, form signature and the delay check methods are less intrusive and do not "punish" your customers. That's why reCAPTCHA appears only if one of the aforementioned validations failed, and we have a reason to suspect that it's a bot, not a human being.
