We've been aware for some time that our open comments policy invited abuse.
Fortunately, that abuse was only occasional and manageable. But lately we have noticed an increase in vicious personal attacks, as well as links posted to disgusting pornography.
As a result, this evening I have enabled a technical feature that allows us to approve comments before they appear on our website.
All legitimate comments will still be published, although it may take a while until you see them.
This includes comments from all viewpoints that voice opinions and criticisms in the strongest possible way. After all, we have always encouraged and appreciated vigorous debate.
It's a shame that a few people had to ruin a healthy open forum. But they deserve our sympathy, not our indignation, because they are truly pathetic.
