WordPressのコメント欄に画像認証を導入する方法

wordpress-logo-hoz-rgb

WordPressへ移行してから1ヶ月半、コメントスパムがかなり酷いです。

Akismetプラグインが100%スパム判断してくれるので実害は無いですが、精神的にあまりよろしくありません。

この手のコメントスパムはロボットプログラムにより自動的に大量に投稿されます。
コメントを投稿する際に、表示された画像の文字を入力させる画像認証を導入すると多くのコメントスパムを防ぐことができます。

コメント欄に画像認証を導入する方法

SI CAPTCHA Anti-Spamプラグインを導入します。

WordPress管理画面>「プラグイン」>「新規追加」から「SI CAPTCHA Anti-Spam」を検索してインストールします。

プラグインを有効化するとコメント欄に画像認証が表示されます。

また、画像認証はWordPressにログインしている状態では表示されません。
一度WordPressからログアウトするとコメント欄に画像認証が表示されます。
