Joi Ito: Comment spam is becoming more "sophisticated". Originally, my policy was to erase stuff that linked to commercial sites if they didn't add to the dialog in the comments. Now comment spammers are actually trying to contribute to the discussion, but still leaving links to their commercial sites. It is much harder to identify as spam. Only by looking at the site that is linked do you realize that it's probably spam.
My suggestion: take a look at the referrer. If they came in from google, and via a query such as "blog comments" or "remember info" or "posted by" (all of which I have received within the past 72 hours), then they most likely are spammer. Unfortunately, few blogging tools present referrer information at this granularity.
Such spammers are what I will call "hit and run artists". This means that a real live person is at a keyboard trying to generally their aim is to game google. Some actually spend the time to appear on topic. I am trying to work out the heuristics for identifying such people.
Anybody want to contribute some anecdotes? How would you complete this sentence...
