Proof-of-Work CAPTCHA

Plugin for CAPTCHA module.

Proof-of-Work will be required to submit form. As a result in order for spammers or bots to submit a lot of spam, they need to spend a lot of CPU cycles which should become not worth it. On top of it most of the spamming software and bots simply can't run JS to do Proof-of-Work at all.

This module uses a few of variables in settings.php to configure environment dependent access list by origin IP.
Use it to limit access to sensitive URLs to only certain IPs (e.g., your office).

The module throws a very unsexy and un-meaningful error message which will be useless for unwanted visitors, but will allow developers and site owners to understand why they are getting it.

This module is perfect to quickly block the possibility of getting to your site's management area if your'e not in a specific place or using the right VPN connection.
