http:BL (Project Honey Pot) spam filter

[Vaclav Slavik <vslavik@…>]

This adds support for the http:BL blacklist maintained by Project Honey Pot. Unlike other blacklists, this is specifically intended for web use From ​http://www.projecthoneypot.org/httpbl.php:

Http:BL is a system that allows website administrators to take advantage of the data generated by Project Honey Pot in order to keep suspicious and malicious web robots off their sites. Project Honey Pot tracks harvesters, comment spammers, and other suspicious visitors to websites. Http:BL makes this data available to any member of Project Honey Pot in an easy and efficient way.

In the past few months, it caught quite a few comment spammers daily on all my Trac installs, unlike the ip_blacklist plugin, which barely ever had a hit.

Implementation note: the code is derived from ip_blacklist, but is not identical (and so I couldn't just add http:BL to the list of blacklists) — http:BL returns some extra information in the reply.

Thanks, I'll test this plugin as well. I am also using Akismet, but a few spam that passed could have been blocked by this plugin.

It misses the admin configuration string to enter the API key. I did in trac.ini, but I guess the admin page should be there eventually.
