I work for a media company who run a large number of forums
There are many cheap tools available to moderate (police) the forum and many different types of moderation e.g. post-moderation (police after the post and delete inappropriate comments) and pre-moderation (posts only appear after checking)
It is incumbent on BT to deploy the right technology and appropriate moderation. They receive the advertising revenue and should be investing it in the right technology and resource to run the forum properly
I have refused to renew my subscription to BT magazine and explained that the conduct of this forum is the reason why. I have voted with my wallet.
The forum is immensely useful and I have learned much about flying from many contributors – for which many thanks.
