Client-side javascript blocks all spam bots. XHTML 1.1 compliant.

== Description ==

= No More Spam =

WP-Hashcash Reloaded is an antispam plugin that eradicates comment spam on WordPress blogs. It works because your visitors must use obfuscated javascript to submit a proof-of-work that indicates they opened your website in a web browser, not a robot. If the javascript check fails, WP Hashcash now gives you three options; it can either put the comment into moderation (default), put the comment in the akismet queue, or delete it.

This is a forked version of the original WP-Hashcash plugin by [Elliott Back](ttp://elliottback.com).

You can read more about the original version at the [WP Hashcash plugin](http://wordpress-plugins.feifei.us/hashcash/) page.

= Features =

1. Blocks all comment spam, but not real comments
2. Also prevents most trackback / pingback spam
3. Also protects signup pages for WordPress (WP), BuddyPress (BP), and WordPress Multi-User (WPMU)
4. Widget support to display spam statistics and edit the configuration
5. Works with IE, Firefox, Chrome, and Safari
6. 100% standards compliant XHTML 1.1, works with jQuery and Prototype
7. Tested with WordPress 3.8, Firefox, Safari, IE, and Chrome
8. Akismet compatibility

= Limitations =

WP Hashcash relies on the presence of two hooks in your theme, `wp_head` and `comment_form`. If your theme doesn't include these actions, you will need to add them immediately before the end head and end form tags respectively.

== Installation ==

= Installation Instructions =

1. To install WP-Hashcash, please download the plugin and unzip it, then copy the wp-hashcash.php file to wp-content/plugins.

= Notes =

If you are upgrading from a previous version of WP-Hashcash, please disabled the plugin, then delete its files entirely.  Then, upload the latest plugin files and activate!
