This plugin automatically scatters invisible links to <a href="http://www.projecthoneypot.org/" rel="nofollow ugc">Project Honey Pot</a> spam traps 
throughout your wordpress blog to help catch and stop spammers.
Project Honey Pot is the first and only distributed system for identifying spammers and the spambots they use 
to scrape addresses from your website. Using the Project Honey Pot system you can install addresses that are 
custom-tagged to the time and IP address of a visitor to your site. If one of these addresses begins receiving 
email Project Honey Pot not only can tell that the messages are spam, but also the exact moment when the address 
was harvested and the IP address that gathered it.
Install this plugin to help contribute to the project and catch spammers by hiding links to honey pots (spam traps) 
in your blog. The links are never visible to human visitors, but the spambots and crawlers follow them straight into 
the traps.
Note: this plugin will not directly prevent spam on your site, but will help prevent spam for everyone by helping to catch the spammers.
If you also want to use the Project Honey Pot API to detect and block spammers from your site, try the <a href="https://wordpress.org/extend/plugins/httpbl/" rel="ugc">http:BL plugin</a>.
<h3>Features</h3>
<ul>
<li>Outputs randomly generated invisible links to honey pots in order to catch spambots</li>

WPBruiser (formerly GoodBye Captcha) is an anti-spam and security plugin based on algorithms that identify spam bots without any annoying and hard to read captcha images.
WPBruiser completely eliminates spam-bot signups, spam comments, even brute force attacks, the second you install it on your WordPress website. It is completely invisible to the end-user – no need to ever fill out a Captcha or other “human-detection” field ever again – and it just works!
Unlike other anti-spam plugins, which detect spam comments and signups after the fact and move them to your spam folder, which you then have to delete – using up not only your website’s resources, but your time as well, WPBruiser prevents the bots from leaving spam in the first place. The result is that your site is not only spam free, it’s faster and more secure.
In addition, WPBruiser is completely self-contained and does not need to connect to any outside service. Your logins remain yours, 100%.
WPBruiser fights Brute Force attacks and eliminates spam-bots on comments, signup pages as well as login and password reset pages. At the click of a button, you can decide which forms to protect.
