Any of my posts in relation to this matter I authorise to be deleted or modified as the administration team see fit. My personal view is all the trolls content should be hidden. If holes then exist in the conversation the Mods could fill in with a disclaimer describing the original post requiring moderation.
The magiea.org forum is one of the most professional and pleasant Linux communities in the world. I'm proud to be a part of it and hope I feel that way for many, many years to come.
