Forgive this radical suggestion, but I'm wondering about how best to deal with the aftermath - all the above stuff is good, but may I tentatively (and in a complete turnaround!) suggest that Dak be *unbanned* (don't panic - keep reading!!), but placed under full moderation, so that everything goes through LO (or some other duly authorised deputy). That way he will be unable to spam multiple posts, add new topics/threads, UNTIL he addresses outstanding issues.. That way he may wish to explain himself, offer any medical excuses he may have, etc.. Plus he will be unable to claim martyrdom anywhere else, and, let's face it, without Apollo deniers (and there are very few left), there won't be much traffic hereabouts...
OK, it was just a thought.. I have moments of madness...
