NP_TypePadAntiSpam

What is this?

NP_TypePadAntiSpam is a plugin that integrates TypePad AntiSpam with Nucleus CMS. TypePad AntiSpam is an Akismet-compatible collaborative spam blocking service from Six Apart.

NP_TypePadAntiSpam は、Nucleus CMS で TypePad AntiSpam を利用できるようにするプラグインです。TypePad AntiSpam は、シックス・アパート社が提供する Akismet 互換の協調スパムフィルターサービスです。

The Code

This program is actually a quick hack based on NP_Akismet. Install the plugin files in your Nucleus plugin directory, and set your TypePad AntiSpam API Key in the admin area. This plugin provides the core anti-spam engine only. It is recommended to use with an anti-spam UI plugin such as NP_Moderate. Japanese language files for NP_Moderate is also available. Put these language files in “moderate/language” directory, and install the plugin.

このプログラムはNP_Akismetを元に少しだけ変更を加えたものです。プラグインのファイルをNucleusのプラグインディレクトリにインストールして、プラグインの管理画面でTypeTypePad AntiSpam APIキーを設定するだけで使えます。このプラグインにはコアとなるスパム防止のエンジンだけが入っています。スパムコメントの管理などのユーザーインターフェースを追加するNP_Moderateなどのプラグインを併用することをお勧めします。 NP_Moderateの日本語ランゲージファイルも用意しました。このランゲージファイルを “moderata/language” ディレクトリにコピーしてから、プラグインのインストールを行ってください。
