A guy named Russ Palmer has created at least three accounts over the past few days, each time answering a single old mold question, recommending that they seek a professional. The first time he included a link which I edited out; it was to a mold company, but I don't remember what. Other times it's just "seek a professional". My guess is he's trying to generate a Google reputation.
How should I respond to this as a reviewer? Should I just start marking any mold-related answer from a new "Russ Palmer" account as spam? (And, I'd be interested in what that first link was to; I can't find it now, I'm guessing because it was deleted.)
