Comments sometimes gets approved, despite being rather obvious spam.

Some comments are approved when they shouldn't. Some observations:

• Certain languages (usually Russian?) seems to have a higher representation of misclassified comments. It may very well be due to a higher representation of spam in these languages ,rather than language related classification issues.
• While a fair number of spam comments slip through, most of them gets rejected and is not shown. What's visible outside admin interface is just a fraction of what's actually submitted.
• Incorrectly approved comments resemble some of the correctly unapproved ones. Not clear why some are considered "ok" while other similar are not.

Possible things to investigate:

• Check initial setup of the demo site in Akismet. Maybe there's issues with site configuration?
• Meta data sent with comments to Akismet, is it correctly collected and formatted by the module (see https://github.com/jensbrak/SpamDetector/blob/master/Zon3.SpamDetector/AkismetSpamDetectorService.cs )?
• Make sure it's not a module/framework bug, ie correctly classified by Akismet but still incorrectly acted upon by this module somehow. Unlikely but not ruled out.

Suggestions are welcome.
