Not to indicate a lack of attention, but I missed it. That being said, is it worth the disruption to suggest exploring some sort of "Abuse" button I see on other websites? There is another system of buttons that look like a thumbs up/thumbs down a reader can select. After x number of thumbs down, the msg is reduced to a link so you need extra effort to see it. A sort of self regulating system.
With that brilliant contribution, I must admit that I've been surprised at how little spam there is on the forum (again, noting that I have missed the most offending program that everyone else saw).
