[spam-stopper] Akismet vs. Spamkarma2 (a solution)

[Sebastian Herp]

Hello list,

first I'd like to introduce myself. I am the average blogger 
(www.sebbi.de) from Germany and recent follower of the Spamkarma2 cult. 
As of now this plugin has never let me down and kept blogging fun 
despite all the spam I receive.

When Matt announced Akismet on his blog I got very excited about the 
idea and had some privacy issues with it. Of course that is relatively 
stupid, because hey ... it's the internet and Google already knows about 
all the comments on my blog ... so what the heck ;-) (but I am still 
wondering why everything that is contained in the array "$_SERVER" has 
to be send to Akismet ... that is a lot more than "just the comment").

Whatever ...

Some bloggers are posting about their switch from Spamkarma to Akismet 
and which one would be better and blabla. I tested Akismet and found it 
to be not worthy to be my only protection, but I know it would 
eventually learn from all the submissions and get better with time. On 
the other side is Spamkarma which is pretty much perfect and can be 
extended to become even more perfect! So I wrote a Spamkarma2 Plugin 
which checks comments against Akismet.com and submits them to their 
database if it's clearly spam or ham. That way Spamkarma improves and 
the Akismet database should also improve ... without user interaction 
and immediatly.

It's currently beta, but works as advertised.

Get it here: http://www.sebbi.de/files/sk2_akismet_plugin.zip

Unzip it into "wp-content/plugins/SK2/sk2_plugins" and enter your 
Wordpress Apikey into "General Settings"->"Akismet Check" in Spamkarma2. 
You can tweak some other advanced settings too if you want (please tell 
me about what works best for you). There is currently no other 
documentation for this plugin plugin (a plugin of a plugin ... oh my 
god!), but I don't it's needed. The concept is simple enough ;-)

Feel free to test it and I'm happy about every feedback I can get. If 
nothing bad comes up (the plugin being a server killer or something), 
I'll release that code to the public this week.

@Matt: the original wordpress-plugin caries no license information. So 
I'd like to know if it is ok to borrow some of the code from it, because 
I have done so. Is it ok?

Greetings and happy halloween,
Sebastian Herp
