Automattic ^[1] Kismet ( Akismet ^[2] for short), is open source software ^[3] that deals with spam in comments and trackbacks on blogs. 

The product is brilliant and has caught most of the comment spam on my WordPress ^[4] blog, but, as is annoyingly typical, the bad guys have worked out the tricks.  [Don’t think for one minute that this makes the bad guys smarter than us; it’s just they get to see what we're doing, we don’t get to see what they are doing - until they’ve done it!]

The way the bad guys are getting around Akismet is by writing short, sweet, and generic comments such as “Hi, very good site”

I’m not sure about other blogging software, but within WordPress, there is an option to moderate comments which I have turned on, and it offers me the above information, asking me whether I want to approve it, or treat it as spam before it is posted.  At a glance, I can easily see that it is spam and delete it.

So for now, I’m getting help from WordPress in dealing with it, but I have much faith in the worlds number 1 Matt ^[6] and Akismet; they’ll work out a solution – fast!
