!!UPDATE!! This plugin is no longer supported/updated as I have joined my
development efforts with Jan Stepien and his original http:BL plugin. Please use
http:BL plugin instead: http://wordpress.org/extend/plugins/httpbl/.
Project Honey Pot Http:BL allows you to verify visitors' IP address against the
Project Honey Pot
database. Using the Http:BL API, this plugin flags, logs, and blocks visitors
with a high threat score, helping you prevent harvesters, spammers, or other
suspicious bots from abusing your blog.
This plugin requires you to sign up for a free account at Project Honey Pot
(http://www.projecthoneypot.org/?rf=45626) so that you can use their Http:BL
API to verify your visitors.
This plugin is based on Jan Stepien's http:BL version 1.4
(http://wordpress.org/extend/plugins/httpbl/).
