Tim Farley has a long, detailed post over here about the latest with intenet troll Dave Mabus (and the events leading up to it). Farley deserves thanks for all his efforts in getting police intervention and in keeping us all posted.
I hope it goes without saying that, annoying as he may be, Mabus needs help... probably psychiatric help, though it's not up to me to try to diagnose him.
I bear the guy no ill will, even though this is one of the sites that he has disrupted from time to time, and despite the fact that some of the material I've received from him in the past has amounted to death threats against me and my family. I think we can conclude by now that he is probably more dangerous to himself than anyone else (though of course, you can never be totally sure - and these situations do need to be treated with some caution).
