No spam in comments. blocked by Invisible internal token-code with ajax.This is not used CAPTCHA.

== Description ==

In English:  

No spam in comments. blocked by Invisible internal token-code with ajax.

This plugin blocks 100% of spam messages in the author of the environment.

It blocks spam without using the CAPTCHA input-field.

There is no modification of display the comment form.

(but the commnet which is posted by spammers manually via browser is not blocked by this plugin)


In Japanese:  

このプラグインはコメント投稿時にAjaxを使ってスパムロボットによる投稿コメントか判別し自動でブロックするプラグインです。

作者の環境では、今のところこのプラグインで100％スパムBOT投稿がブロックできています。

一般的なスパム対策としてAkismetプラグインがありますがブロックされるのは９割程度で100%は止まりませんでした。

別の方法としてCAPTCHA系のプラグインを使いBot対策する手段もありますが、こちらはほぼ100%スパムBotからの投稿はブロックされますがユーザーに煩わしい確認文字入力に毎回協力してもらう必要がありました。 このプラグインでは、見えない入力欄を用意してコメント投稿時にjavascriptでCAPTCHA入力に変わる固有の確認トークン入力処理をで行うことでスパムBotからの投稿をブロックします。

利用ユーザーのコメントフォームの見え方は変わりません。 

(残念ながらこのプラグインではブラウザを介した手入力によるスパム投稿はブロックできません)
