Three Strikes and You’re Out examines your Bad Behavior logs and your WordPress 
spam queue and closes comments on all blog entries across the board to IP 
addresses that have reported three or more attempts at mischief over the past 
seven days.
It also has an additional logging feature and an API that allows other plugins 
to register certain events as being mischievous.
<h3>Configuration</h3>
By default, Three Strikes and You’re Out closes comments right across the board 
on your blog to any IP address that has attempted any mischief three or more 
times in the past week. You can change these by editing the two defined 
constants at the top of the plugin file, just below the copyright notice. There 
are three such defines:
<ul>
<li><code>THREE_STRIKES_LIMIT</code> is the number of bad hits at which to block comments.</li>
<li><code>THREE_STRIKES_TIMEOUT</code> is the time in seconds after which bad hits are no 
longer considered.</li>
<li><code>THREE_STRIKES_BB_STRICT</code> indicates that you should consider any “strict” 
events recorded in the Bad Behavior log. These are events that are blocked when 
Bad Behavior is using the “strict checking” option, but would be ignored 
otherwise.</li>
</ul>
<h3>The Three Strikes API</h3>
This plugin includes a number of hooks that allow other plugins to communicate 
with it. These are implemented as actions and filters, so if Three Strikes is 
not installed, your plugin will continue to function.

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)
