I probably should have phrased my remarks differently. I usually try very hard not to use the second personal pronoun and "spam" in the same sentence, so that I can address the general issue in the light of our editor experience. And, despite the personal pronoun, I really was thinking in the general, not the specific case.
We have seen, and continue to see, spammeisters who build cookie-cutter sites for one city after another, with a sentence or two of "local information", and deeplinks to lots and lots of profitable affiliate programs -- florists, hotel reservations, etc, etc, etc. Some of them at least show the deeplinks honestly. But more and more of these cyanobacteria, knowing they've well worn their welcome out, go to great lengths to conceal the nature of the site ownership and affiliate links. This is probably the single largest source of spam in the Regional categories. So, when experienced editors see a content-lite "city directory", they simply and automatically wonder which of the poisoned-cookie-cutter spammers it belongs to. A loss for people who are just beginning to build up a "fan site" for their hometown; a loss for surfers and directory builders.
Another way of putting it is that the spammers are systematically doing their dead-level best to destroy the value of the internet for everyone, and are certainly having more success at that than they could be at any task that requires room-temperature IQ or alley-cat morals.
