What? Is this separate from the recent Banned Post? Is this a different idea?
It was a counter argument against the dangerous topic being dangerous, which by necessity touched the dangerous topic and which wasn't strong enough to justify this (anyone for whom the dangerous topic actually would be dangerous [rather than just causing nightmares] would almost by necessity already be aware of a stronger argument).
Some research says that lurkers make up over 90% of online groups. I suspect that Less Wrong has an even higher percentage of lurkers than other online communities.
