The issues with Scott on the board itself are different to his presence in other forums.
No only has he made truly horrible accusations against other boarders, as well as grossly insensitive remarks, but his presence, or as in this case even the suspicion of his presence, plunges the board into 'I don't see what's so bad about him really' and 'FOAD Scott' camps, and then subsequently the 'it's unseemly the way you fixate on that guy when he obviously has real problems' and 'he's forum cancer' camps. Not pretty at all.
It also leads to the same old discussions in almost every thread, usually centering on Why John Wagner is Wrong and Why Rebellion Are Idiots - but that's universal where'ere he goes.
My other concern at the moment would be that the requirement for new boarders to have a certain track record before being allowed post on the Movie discussions would be an incentive for Scott's potential next identity to spew endless short innocuous posts as a way to get around it - leading to suspicion falling on new people with such a posting pattern. Not sure that can be helped.
Either way, it's been decided that he is permanently banned, so a note to the mods to check out candidates (as initially suggested by Locusts) is probably preferable to This Thread Mk. XXVII.
