## Installation ##
* If you don’t know how to install a plugin for WordPress, [here’s how](http://codex.wordpress.org/Managing_Plugins#Installing_Plugins).

### Requirements ###
* PHP 5.2.4 or greater
* WordPress 4.5 or greater

### Settings ###
After you have activated *Antispam Bee* the plugin will block spam comments out of the box. However, you may want to visit *Settings → Antispam Bee* to configure your custom set of anti-spam options that works best for your site.

## Frequently Asked Questions ##

### Does Antispam Bee prevents spam registrations or protects form plugins? ###
Antispam Bee works best with default WordPress comments. It does not help to protect form plugins and does not prevent spam registrations. Hopefully we can provide better hooks for third party plugins to use Antispam Bee to fill this gap in the forthcoming new major version.

### Does Antispam Bee work with Jetpack, Disqus Comments and other comment plugins? ###
Antispam Bee works best with default WordPress comments. It is not compatible with Jetpack or Disqus Comments as those plugins load the comment form within an iframe. Thus Antispam Bee can not access the comment form directly.
It also won’t work with any AJAX-powered comment forms.

### Does Antispam Bee store any private user data, and is it compliant with GDPR? ###
Antispam Bee is developed in Europe. You might have heard we can be a bit nitpicky over here when it comes to privacy. The plugin does not save private user data and is 100% compliant with GDPR.

### Will I have to edit any theme templates to get Antispam Bee to work? ###
No, the plugin works as is. You may want to configure your favorite settings, though.

### Does Antispam Bee work with shortened IPs? ###
Generally yes. However, commissioning the Antispam Bee plugin for canceled or shortened IP addresses in comment metadata is not recommended. Because the name and the e-mail address of the comments are not unique, an IP address is the only reliable measure. The more complete the stored IP addresses, the more reliable the assignment or detection of spam.

### How can I submit undetected spam? ###
If the antispam plugin has passed some spam comments, these comments can be reported for analysis. A [Google table](http://goo.gl/forms/ITzVHXkLVL) was created for this purpose.

### Antispam Bee with Varnish? ###
If WordPress is operated with Apache + Varnish, the actual IP address of the visitors does not appear in WordPress. Accordingly the Antispam-Plugin lacks the base for the correct functionality. An adaptation in the Varnish configuration file /etc/varnish/default.vcl provides a remedy and forwards the original (not from Apache) IP address in the HTTP header X-Forwarded-For:

> if (req.restarts == 0) {
>     set req.http.X-Forwarded-For = client.ip;
> }

### Are there some paid services or limitations? ###
No, Antispam Bee is free forever, for both private and commercial projects. You can use it on as many sites as you want. There is no limitation to the number of sites you use the plugin on.

A complete documentation is available on [pluginkollektiv.org](https://antispambee.pluginkollektiv.org/documentation/).
