Really? That's the best analogy you could come up with? It's more like a newspaper printing advertisements that there will be stolen radios for sale or prostitutes behind the Walmart on Saturday.
Poor analogy. Unless there are other mechanisms in place, a link doesn't serve an advertising purpose any more or less than a purely informational one. I would like for a newspaper engage in activities like exposing fences or street prostitution. I believe that's called "reporting."
