Drupal Spamモジュール追加

Trackback Spam が多くなってきたので Spam module を追加してみました。
本家のほうのモジュールは古いみたいなので、以下のページから

The Drupal Spam Module 2.0

ファイルをダウンロードして、SQLを流して、モジュールをコピーするだけ。
うまく動いているかもよくわかりませんが、とりあえず特徴としては以下のようです。

  • Written in PHP specifically for Drupal.
  • Highly configurable.
  • Automatically detects and unpublishes spam comments and other spam content.
  • Automatically learns to detect spam in any language using Bayesian logic.
  • Automatically learns and blocks spammer URLs.
  • Automatically blacklists IPs of learned spammers, preventing them from posting additional spam and wasting database resources.
  • Detects repeated postings of the same identical content.
  • Detects content containing too many links, or the same link over and over.
  • Supports the creation of custom filters using powerful regular expressions.
  • Can notify the user that his or her content was determined to be spam, preventing confusion over why their content doesn't show up.
  • Can notify the site administrator in an email when spam is detected.
  • Provides simple administrative interfaces for reviewing spam content.
  • Provides comprehensive logging to offer an understanding as to how and why content is determined to be or not to be spam.

    SMTPとおなじでTrackbackも性善説に基づいて作られた仕様とのこと。
    早くよい仕組みが考えられるといいですね。
