159	+ <p>The CSS file loads at the top of the page, possibly slowing down how fast the page renders. The image loads at the end but if your server is very slow someone may have time to enter a comment before the image loads. Unlikely but it might happen.</p>
160	+ <h3>Speed Spammers</h3>
161	+
162	+ <p>Some spammers visit your site, leave a real looking comment and disappear again. They'll do this quickly and then move on to the next target site.<br /> To stop them we check how long they spend on your site before leaving the comment. Any value above 0 will reject those comments but might catch legitimate comments too. Recommended values from 3 to 6 seconds and send comments to the spam folder.</p>

166	+ <p>When a comment fails to be posted it's not always a spammer. Add a message here to be shown to those users. Be aware that real spammers will see this message too! The comment they made will be shown below your message.</p>

10	== Description ==
11	+ This plugin adds a stylesheet or image to your blog's html source code. When a browser loads that stylesheet or image a cookie is dropped. If that user then leaves a comment the cookie is checked. If it doesn't exist the comment is marked as spam.
12	+ The plugin can also check how long it took a user to enter a comment. If it's too fast it's probably a spam bot. How fast can a legitimate user enter their name, email, web address and enter a well thought out comment?
