The "funky field names" for comments should be (a) randomly generated on installation and (b) user-definable via the back office. I've already gotten automated spam, so I figure 'they' either downloaded 1.8 to learn what to do or stripped the source to find the field names. Or something! Anyway if they were automagically unique and customizable on each installation the spammers would be forced - FORCED! - to go get real jobs.
