I doubt the moderators have asked posters to cool it! I think it's more to do with a number of posters being banned or deleted. Those posters were often thought provoking and sometimes unfortunately very unpleasant. This meant some regular posters stopped posting and therefore there was a lack of debate. It's a shame really because it should be possible to express a variety of views without becoming abusive. It's a problem the old WhiteBallProject had, and I must put my hand up and admit I did not administer it well enough and perhaps I trusted people too much!
