Maybe we should ask Nihil.

There have been times when a thread gets interesting as could be surmised from the number of responses posted but eventually, Nihil sniffs them out and the trolls get blown and banned.

One possible reason why the trolls don't come around that often is that the antipoints don't matter much anymore which means the more sane and informative topics get posted even though some of these wallow to oblivion--so to speak--when the responses become too sparse.
